These methods only called a single function. Wrappers like this end up making code harder to read
because it adds extra ways of doing things.
We already have many helper functions for constructing these types, we don't need additional methods.
structs.ACLForceSet was deprecated 4 years ago, it should be safe to remove now.
ACLBootstrapNow was removed in a recent commit. While it is technically possible that a cluster with mixed version
could still attempt a legacy boostrap, we documented that the legacy system was deprecated in 1.4, so no
clusters that are being upgraded should be attempting a legacy boostrap.

* agent: add failures_before_warning setting
The new setting allows users to specify the number of check failures
that have to happen before a service status us updated to be `warning`.
This allows for more visibility for detected issues without creating
alerts and pinging administrators. Unlike the previous behavior, which
caused the service status to not update until it reached the configured
`failures_before_critical` setting, now Consul updates the Web UI view
with the `warning` state and the output of the service check when
`failures_before_warning` is breached.
The default value of `FailuresBeforeWarning` is the same as the value of
`FailuresBeforeCritical`, which allows for retaining the previous default
behavior of not triggering a warning.
When `FailuresBeforeWarning` is set to a value higher than that of
`FailuresBeforeCritical it has no effect as `FailuresBeforeCritical`
takes precedence.

Some users are defining routing configurations that do not have associated services. This commit surfaces these configs in the topology visualization. Also fixes a minor internal bug with non-transparent proxy upstream/downstream references.
- The TestNodeService helper created services with the fixed name "web",
and now that name is overridable.
- The discovery chain snapshot didn't have prepared query endpoints so
the endpoints tests were missing data for prepared queries

Renames all variables for acl.Authorizer to use `authz`. Previously some
places used `rule` which I believe was an old name carried over from the
legacy ACL system.
A couple places also used authorizer.
This commit also removes another couple of authorizer nil checks that
are no longer necessary.

Move the check for the Intention.DestinationName into the Authorizer to remove the
need to check what kind of Authorizer is being used.
It sounds like this check is only for legacy ACLs, so is probably just a safeguard
.
CatalogDestinationsOnly is a passthrough that would enable dialing
addresses outside of Consul's catalog. However, when this flag is set to
true only _connect_ endpoints for services can be dialed.
This flag is being renamed to signal that non-Connect endpoints can't be
dialed by transparent proxies when the value is set to true.
Previously we would return an error if duplicate paths were specified.
This could lead to problems in cases where a user has the same path,
say /healthz, on two different ports.
This validation was added to signal a potential misconfiguration.
Instead we will only check for duplicate listener ports, since that is
what would lead to ambiguity issues when generating xDS config.
In the future we could look into using a single listener and creating
distinct filter chains for each path/port.
The prior solution to call reply.Reset() aged poorly since newer fields
were added to the reply, but not added to Reset() leading serial
blocking query loops on the server to blend replies.
This could manifest as a service-defaults protocol change from
default=>http not reverting back to default after the config entry
reponsible was deleted.
* Save exposed HTTP or GRPC ports to the agent's store
* Add those the health checks API so we can retrieve them from the API
* Change redirect-traffic command to also exclude those ports from inbound traffic redirection when expose.checks is set to true.
Also fixes a bug with listing kind=mesh config entries. ValidateConfigEntryKind was only being used by
the List endpoint, and was yet another place where we have to enumerate all the kinds.
This commit removes ValidateConfigEntryKind and uses MakeConfigEntry instead. This change removes
the need to maintain two separate functions at the cost of creating an instance of the config entry which will be thrown away immediately.

Previously we would associate the address of a discovery chain target
with the discovery chain's filter chain. This was broken for a few reasons:
- If the upstream is a virtual service, the client proxy has no way of
dialing it because virtual services are not targets of their discovery
chains. The targets are distinct services. This is addressed by watching
the endpoints of all upstream services, not just their discovery chain
targets.
- If multiple discovery chains resolve to the same target, that would
lead to multiple filter chains attempting to match on the target's
virtual IP. This is addressed by only matching on the upstream's virtual
IP.
NOTE: this implementation requires an intention to the redirecting
virtual service and not just to the final destination. This is how
we can know that the virtual service is an upstream to watch.
A later PR will look into traversing discovery chains when computing
upstreams so that intentions are only required to the discovery chain
targets.
No config entry needs a Kind field. It is only used to determine the Go type to
target. As we introduce new config entries (like this one) we can remove the kind field
and have the GetKind method return the single supported value.
In this case (similar to proxy-defaults) the Name field is also unnecessary. We always
use the same value. So we can omit the name field entirely.
This config entry is being renamed primarily because in k8s the name
cluster could be confusing given that the config entry applies across
federated datacenters.
Additionally, this config entry will only apply to Consul as a service
mesh, so the more generic "cluster" name is not needed.
This way we avoid serializing these when empty. Otherwise users of the
latest version of the api submodule cannot interact with older versions
of Consul, because a new api client would send keys that the older Consul
doesn't recognize yet.
The zero value of these flags was already being excluded in the xDS
generation of circuit breaker/outlier detection config.
See: makeThresholdsIfNeeded and ToOutlierDetection.
This PR replaces the original boolean used to configure transparent
proxy mode. It was replaced with a string mode that can be set to:
- "": Empty string is the default for when the setting should be
defaulted from other configuration like config entries.
- "direct": Direct mode is how applications originally opted into the
mesh. Proxy listeners need to be dialed directly.
- "transparent": Transparent mode enables configuring Envoy as a
transparent proxy. Traffic must be captured and redirected to the
inbound and outbound listeners.
This PR also adds a struct for transparent proxy specific configuration.
Initially this is not stored as a pointer. Will revisit that decision
before GA.

* add H2PING to protocol buffers and update changelog
* fix typo in changelog entry
This is needed in case the client proxy is in TransparentProxy mode.
Typically they won't have explicit configuration for every upstream, so
this ensures the settings can be applied to all of them when generating
xDS config.
Some TLS servers require SNI, but the Golang HTTP client doesn't
include it in the ClientHello when connecting to an IP address. This
change adds a new TLSServerName field to health check definitions to
optionally set it. This fixes#9473.
ResolveServiceConfig is called by service manager before the proxy
registration is in the catalog. Therefore we should pass proxy
registration flags in the request rather than trying to fetch
them from the state store (where they may not exist yet).
This is done because after removing ID and NodeName from
ServiceConfigRequest we will no longer know whether a request coming in
is for a Consul client earlier than v1.10.
Previously this type was defined in structs, but unlike the other types in structs this type
is not used by RPC requests. By moving it to state we can better indicate that this is not
an API type, but part of the state implementation.
I added this recently without realizing that the method already existed and was named
NamespaceOrEmpty. Replace all calls to GetNamespace with NamespaceOrEmpty or NamespaceOrDefault
as appropriate.
Previous to this commit, the API response would include Gateway
Addresses in the form `domain.name.:8080`, which due to the addition of
the port is probably not the expected response.
This commit rightTrims any `.` characters from the end of the domain
before formatting the address to include the port resulting in
`domain.name:8080`
* A GET of the /acl/auth-method/:name endpoint returns the fields
MaxTokenTTL and TokenLocality, while a LIST (/acl/auth-methods) does
not.
The list command returns a filtered subset of the full set. This is
somewhat deliberate, so that secrets aren't shown, but the TTL and
Locality fields aren't (IMO) security critical, and it is useful for
the front end to be able to show them.
For consistency these changes mirror the 'omit empty' and string
representation choices made for the GET call.
This includes changes to the gRPC and API code in the client.
The new output looks similar to this
curl 'http://localhost:8500/v1/acl/auth-methods' | jq '.'
