The grpc resolver implementation is fed from changes to the
router.Router. Within the router there is a map of various areas storing
the addressing information for servers in those areas. All map entries
are of the WAN variety except a single special entry for the LAN.
Addressing information in the LAN "area" are local addresses intended
for use when making a client-to-server or server-to-server request.
The client agent correctly updates this LAN area when receiving lan serf
events, so by extension the grpc resolver works fine in that scenario.
The server agent only initially populates a single entry in the LAN area
(for itself) on startup, and then never mutates that area map again.
For normal RPCs a different structure is used for LAN routing.
Additionally when selecting a server to contact in the local datacenter
it will randomly select addresses from either the LAN or WAN addressed
entries in the map.
Unfortunately this means that the grpc resolver stack as it exists on
server agents is either broken or only accidentally functions by having
servers dial each other over the WAN-accessible address. If the operator
disables the serf wan port completely likely this incidental functioning
would break.
This PR enforces that local requests for servers (both for stale reads
or leader forwarded requests) exclusively use the LAN "area" information
and also fixes it so that servers keep that area up to date in the
router.
A test for the grpc resolver logic was added, as well as a higher level
full-stack test to ensure the externally perceived bug does not return.

Fix multiple issues related to proxycfg health queries.
1. The datacenter was not being provided to a proxycfg query, which resulted in
bypassing agentless query optimizations and using the normal API instead.
2. The health rpc endpoint would return a zero index when insufficient ACLs were
detected. This would result in the agent cache performing an infinite loop of
queries in rapid succession without backoff.
Fix issue with peer stream node cleanup.
This commit encompasses a few problems that are closely related due to their
proximity in the code.
1. The peerstream utilizes node IDs in several locations to determine which
nodes / services / checks should be cleaned up or created. While VM deployments
with agents will likely always have a node ID, agentless uses synthetic nodes
and does not populate the field. This means that for consul-k8s deployments, all
services were likely bundled together into the same synthetic node in some code
paths (but not all), resulting in strange behavior. The Node.Node field should
be used instead as a unique identifier, as it should always be populated.
2. The peerstream cleanup process for unused nodes uses an incorrect query for
node deregistration. This query is NOT namespace aware and results in the node
(and corresponding services) being deregistered prematurely whenever it has zero
default-namespace services and 1+ non-default-namespace services registered on
it. This issue is tricky to find due to the incorrect logic mentioned in #1,
combined with the fact that the affected services must be co-located on the same
node as the currently deregistering service for this to be encountered.
3. The stream tracker did not understand differences between services in
different namespaces and could therefore report incorrect numbers. It was
updated to utilize the full service name to avoid conflicts and return proper
results.

When using vault as a CA and generating the local signing cert, try to
enable the PKI endpoint's auto-tidy feature with it set to tidy expired
issuers.
This adds filtering for service-defaults: consul config list -filter 'MutualTLSMode == "permissive"'.
It adds CLI warnings when the CLI writes a config entry and sees that either service-defaults or proxy-defaults contains MutualTLSMode=permissive, or sees that the mesh config entry contains AllowEnablingPermissiveMutualTLSMode=true.
Partitioned downstreams with peered upstreams could not properly merge central config info (i.e. proxy-defaults and service-defaults things like mesh gateway modes) if the upstream had an empty DestinationPartition field in Enterprise.
Due to data flow, if this setup is done using Consul client agents the field is never empty and thus does not experience the bug.
When a service is registered directly to the catalog as is the case for consul-dataplane use this field may be empty and and the internal machinery of the merging function doesn't handle this well.
This PR ensures the internal machinery of that function is referentially self-consistent.
* Persist HCP management token from server config
We want to move away from injecting an initial management token into
Consul clusters linked to HCP. The reasoning is that by using a separate
class of token we can have more flexibility in terms of allowing HCP's
token to co-exist with the user's management token.
Down the line we can also more easily adjust the permissions attached to
HCP's token to limit it's scope.
With these changes, the cloud management token is like the initial
management token in that iit has the same global management policy and
if it is created it effectively bootstraps the ACL system.
* Update SDK and mock HCP server
The HCP management token will now be sent in a special field rather than
as Consul's "initial management" token configuration.
This commit also updates the mock HCP server to more accurately reflect
the behavior of the CCM backend.
* Refactor HCP bootstrapping logic and add tests
We want to allow users to link Consul clusters that already exist to
HCP. Existing clusters need care when bootstrapped by HCP, since we do
not want to do things like change ACL/TLS settings for a running
cluster.
Additional changes:
* Deconstruct MaybeBootstrap so that it can be tested. The HCP Go SDK
requires HTTPS to fetch a token from the Auth URL, even if the backend
server is mocked. By pulling the hcp.Client creation out we can modify
its TLS configuration in tests while keeping the secure behavior in
production code.
* Add light validation for data received/loaded.
* Sanitize initial_management token from received config, since HCP will
only ever use the CloudConfig.MangementToken.
* Add changelog entry

This implements permissive mTLS , which allows toggling services into "permissive" mTLS mode.
Permissive mTLS mode allows incoming "non Consul-mTLS" traffic to be forward unmodified to the application.
* Update service-defaults and proxy-defaults config entries with a MutualTLSMode field
* Update the mesh config entry with an AllowEnablingPermissiveMutualTLS field and implement the necessary validation. AllowEnablingPermissiveMutualTLS must be true to allow changing to MutualTLSMode=permissive, but this does not require that all proxy-defaults and service-defaults are currently in strict mode.
* Update xDS listener config to add a "permissive filter chain" when MutualTLSMode=permissive for a particular service. The permissive filter chain matches incoming traffic by the destination port. If the destination port matches the service port from the catalog, then no mTLS is required and the traffic sent is forwarded unmodified to the application.

Prior to this change, peer services would be targeted by service-default
overrides as long as the new `peer` field was not found in the config entry.
This commit removes that deprecated backwards-compatibility behavior. Now
it is necessary to specify the `peer` field in order for upstream overrides
to apply to a peer upstream.
Currently, if an acceptor peer deletes a peering the dialer's peering
will eventually get to a "terminated" state. If the two clusters need to
be re-peered the acceptor will re-generate the token but the dialer will
encounter this error on the call to establish:
"failed to get addresses to dial peer: failed to refresh peer server
addresses, will continue to use initial addresses: there is no active
peering for "<<<ID>>>""
This is because in `exchangeSecret().GetDialAddresses()` we will get an
error if fetching addresses for an inactive peering. The peering shows
up as inactive at this point because of the existing terminated state.
Rather than checking whether a peering is active we can instead check
whether it was deleted. This way users do not need to delete terminated
peerings in the dialing cluster before re-establishing them.

This commit swaps the partition field to the local partition for
discovery chains targeting peers. Prior to this change, peer upstreams
would always use a value of default regardless of which partition they
exist in. This caused several issues in xds / proxycfg because of id
mismatches.
Some prior fixes were made to deal with one-off id mismatches that this
PR also cleans up, since they are no longer needed.

This commit fixes an issue where trust bundles could not be read
by services in a non-default namespace, unless they had excessive
ACL permissions given to them.
Prior to this change, `service:write` was required in the default
namespace in order to read the trust bundle. Now, `service:write`
to a service in any namespace is sufficient.
If a CA config update did not cause a root change, the codepath would return early and skip some steps which preserve its intermediate certificates and signing key ID. This commit re-orders some code and prevents updates from generating new intermediate certificates.

Add a new envoy flag: "envoy_hcp_metrics_bind_socket_dir", a directory
where a unix socket will be created with the name
`<namespace>_<proxy_id>.sock` to forward Envoy metrics.
If set, this will configure:
- In bootstrap configuration a local stats_sink and static cluster.
These will forward metrics to a loopback listener sent over xDS.
- A dynamic listener listening at the socket path that the previously
defined static cluster is sending metrics to.
- A dynamic cluster that will forward traffic received at this listener
to the hcp-metrics-collector service.
Reasons for having a static cluster pointing at a dynamic listener:
- We want to secure the metrics stream using TLS, but the stats sink can
only be defined in bootstrap config. With dynamic listeners/clusters
we can use the proxy's leaf certificate issued by the Connect CA,
which isn't available at bootstrap time.
- We want to intelligently route to the HCP collector. Configuring its
addreess at bootstrap time limits our flexibility routing-wise. More
on this below.
Reasons for defining the collector as an upstream in `proxycfg`:
- The HCP collector will be deployed as a mesh service.
- Certificate management is taken care of, as mentioned above.
- Service discovery and routing logic is automatically taken care of,
meaning that no code changes are required in the xds package.
- Custom routing rules can be added for the collector using discovery
chain config entries. Initially the collector is expected to be
deployed to each admin partition, but in the future could be deployed
centrally in the default partition. These config entries could even be
managed by HCP itself.
Add support for using existing vault auto-auth configurations as the
provider configuration when using Vault's CA provider with AliCloud.
AliCloud requires 2 extra fields to enable it to use STS (it's preferred
auth setup). Our vault-plugin-auth-alicloud package contained a method
to help generate them as they require you to make an http call to
a faked endpoint proxy to get them (url and headers base64 encoded).
