Daniel Nephin b4a10443d1 ca: remove unused RotationPeriod field
This field was never used. Since it is persisted as part of a map[string]interface{} it
is pretty easy to remove it.

Daniel Nephin 843e08bb23 testing: fix a test for 32-bit
The hcl decoding apparently uses strconv.ParseInt, which fails to parse a 64bit int.
Since hcl v1 is basically EOl, it seems unlikely we'll fix this in hcl.

Since this test is only about loading values from config files, the extra large number
doesn't seem important. Trim a few zeros from the numbers so that they parse
properly on 32bit platforms.

Also skip a slow test when -short is used.

Daniel Nephin 0a39ba2c54 envoy: fix bootstrap deadlock caused by a full named pipe
Normally the named pipe would buffer up to 64k, but in some cases when a
soft limit is reached, they will start only buffering up to 4k.
In either case, we should not deadlock.

This commit changes the pipe-bootstrap command to first buffer all of
stdin into the process, before trying to write it to the named pipe.
This allows the process memory to act as the buffer, instead of the
named pipe.

Also changed the order of operations in `makeBootstrapPipe`. The new
test added in this PR showed that simply buffering in the process memory
was not enough to fix the issue. We also need to ensure that the
`pipe-bootstrap` process is started before we try to write to its
stdin. Otherwise the write will still block.

Also set stdout/stderr on the subprocess, so that any errors are visible
to the user.

Daniel Nephin f079cef352 redirecttraffic: fix a flaky test
https://app.circleci.com/pipelines/github/hashicorp/consul-enterprise/6408/workflows/e90b1140-daa2-458f-8197-d1821e3693e3/jobs/94694/tests#failed-test-0

The ExcludeInboundPorts can be in a different order sometimes, although I'm not sure how.

Also removes t.Parallel. We should only need to use t.Parallel in large packages with many slow tests.
In this case there is only a single slow test so we don't get any benefit.

Also add struct field names to the testcases list, so that it is easier to see what
each value is doing, and to make it easier to add new fields in the future.

connect: update supported envoy versions to 1.18.2, 1.17.2, 1.16.3, and 1.15.4 (#10101)
The only thing that needed fixing up pertained to this section of the 1.18.x release notes:

> grpc_stats: the default value for stats_for_all_methods is switched from true to false, in order to avoid possible memory exhaustion due to an untrusted downstream sending a large number of unique method names. The previous default value was deprecated in version 1.14.0. This only changes the behavior when the value is not set. The previous behavior can be used by setting the value to true. This behavior change by be overridden by setting runtime feature envoy.deprecated_features.grpc_stats_filter_enable_stats_for_all_methods_by_default.

For now to maintain status-quo I'm explicitly setting `stats_for_all_methods=true` in all versions to avoid relying upon the default.

Additionally the naming of the emitted metrics for these gRPC requests changed slightly so the integration test assertions for `case-grpc` needed adjusting.

Support Incremental xDS mode (#9855)
This adds support for the Incremental xDS protocol when using xDS v3. This is best reviewed commit-by-commit and will not be squashed when merged.

Union of all commit messages follows to give an overarching summary:

xds: exclusively support incremental xDS when using xDS v3

Attempts to use SoTW via v3 will fail, much like attempts to use incremental via v2 will fail.
Work around a strange older envoy behavior involving empty CDS responses over incremental xDS.
xds: various cleanups and refactors that don't strictly concern the addition of incremental xDS support

Dissolve the connectionInfo struct in favor of per-connection ResourceGenerators instead.
Do a better job of ensuring the xds code uses a well configured logger that accurately describes the connected client.
xds: pull out checkStreamACLs method in advance of a later commit

xds: rewrite SoTW xDS protocol tests to use protobufs rather than hand-rolled json strings

In the test we very lightly reuse some of the more boring protobuf construction helper code that is also technically under test. The important thing of the protocol tests is testing the protocol. The actual inputs and outputs are largely already handled by the xds golden output tests now so these protocol tests don't have to do double-duty.

This also updates the SoTW protocol test to exclusively use xDS v2 which is the only variant of SoTW that will be supported in Consul 1.10.

xds: default xds.Server.AuthCheckFrequency at use-time instead of construction-time

Implement traffic redirection exclusion based on proxy config and user-provided values (#10134)
* Use proxy outbound port from TransparentProxyConfig if provided
* If -proxy-id is provided to the redirect-traffic command, exclude any listener ports
  from inbound traffic redirection. This includes envoy_prometheus_bind_addr,
  envoy_stats_bind_addr, and the ListenerPort from the Expose configuration.
* Allow users to provide additional inbound and outbound ports, outbound CIDRs
  and additional user IDs to be excluded from traffic redirection.

Add flags to consul connect envoy for metrics merging. (#9768)
Allows setting -prometheus-backend-port to configure the cluster
envoy_prometheus_bind_addr points to.

Allows setting -prometheus-scrape-path to configure which path
envoy_prometheus_bind_addr exposes metrics on.

-prometheus-backend-port is used by the consul-k8s metrics merging feature, to
configure envoy_prometheus_bind_addr to point to the merged metrics
endpoint that combines Envoy and service metrics so that one set of
annotations on a Pod can scrape metrics from the service and it's Envoy
sidecar.

-prometheus-scrape-path is used to allow configurability of the path
where prometheus metrics are exposed on envoy_prometheus_bind_addr.

xds: remove deprecated usages of xDS (#9602)
Note that this does NOT upgrade to xDS v3. That will come in a future PR.

Additionally:

- Ignored staticcheck warnings about how github.com/golang/protobuf is deprecated.
- Shuffled some agent/xds imports in advance of a later xDS v3 upgrade.
- Remove support for envoy 1.13.x but don't add in 1.17.x yet. We have to wait until the xDS v3 support is added in a follow-up PR.

connect: intentions are now managed as a new config entry kind "service-intentions" (#8834)
- Upgrade the ConfigEntry.ListAll RPC to be kind-aware so that older
copies of consul will not see new config entries it doesn't understand
replicate down.

- Add shim conversion code so that the old API/CLI method of interacting
with intentions will continue to work so long as none of these are
edited via config entry endpoints. Almost all of the read-only APIs will
continue to function indefinitely.

- Add new APIs that operate on individual intentions without IDs so that
the UI doesn't need to implement CAS operations.

- Add a new serf feature flag indicating support for
intentions-as-config-entries.

- The old line-item intentions way of interacting with the state store
will transparently flip between the legacy memdb table and the config
entry representations so that readers will never see a hiccup during
migration where the results are incomplete. It uses a piece of system
metadata to control the flip.

- The primary datacenter will begin migrating intentions into config
entries on startup once all servers in the datacenter are on a version
of Consul with the intentions-as-config-entries feature flag. When it is
complete the old state store representations will be cleared. We also
record a piece of system metadata indicating this has occurred. We use
this metadata to skip ALL of this code the next time the leader starts
up.

- The secondary datacenters continue to run the old intentions
replicator until all servers in the secondary DC and primary DC support
intentions-as-config-entries (via serf flag). Once this condition it met
the old intentions replicator ceases.

- The secondary datacenters replicate the new config entries as they are
migrated in the primary. When they detect that the primary has zeroed
it's old state store table it waits until all config entries up to that
point are replicated and then zeroes its own copy of the old state store
table. We also record a piece of system metadata indicating this has
occurred. We use this metadata to skip ALL of this code the next time
the leader starts up.

Fix envoy bootstrap logic to not append multiple self_admin clusters (#8371)
Previously, the envoy bootstrap config would blindly copy the self_admin

Since ingress gateways always configure the ReadyBindAddr property,
users ran into this case much more often than previously.

Highlights:

- add new endpoint to query for intentions by exact match

- using this endpoint from the CLI instead of the dump+filter approach

- enforcing that OSS can only read/write intentions with a SourceNS or
  DestinationNS field of "default".

- preexisting OSS intentions with now-invalid namespace fields will
  delete those intentions on initial election or for wildcard namespaces
  an attempt will be made to downgrade them to "default" unless one
  exists.

- also allow the '-namespace' CLI arg on all of the intention subcommands

- update lots of docs

Implement Client Agent Auto Config
There are a couple of things in here.

First, just like auto encrypt, any Cluster.AutoConfig RPC will implicitly use the less secure RPC mechanism.

This drastically modifies how the Consul Agent starts up and moves most of the responsibilities (other than signal handling) from the cli command and into the Agent.
