Adds support for the approle auth-method. Only handles using the approle
role/secret to auth and it doesn't support the agent's extra management
configuration options (wrap and delete after read) as they are not
required as part of the auth (ie. they are vault agent things).

Adds support for a jwt token in a file. Simply reads the file and sends
the read in jwt along to the vault login.
It also supports a legacy mode with the jwt string being passed
directly. In which case the path is made optional.
Does the required dance with the local HTTP endpoint to get the required
data for the jwt based auth setup in Azure. Keeps support for 'legacy'
mode where all login data is passed on via the auth methods parameters.
Refactored check for hardcoded /login fields.
Registering gRPC balancers is thread-unsafe because they are stored in a
global map variable that is accessed without holding a lock. Therefore,
it's expected that balancers are registered _once_ at the beginning of
your program (e.g. in a package `init` function) and certainly not after
you've started dialing connections, etc.
> NOTE: this function must only be called during initialization time
> (i.e. in an init() function), and is not thread-safe.
While this is fine for us in production, it's challenging for tests that
spin up multiple agents in-memory. We currently register a balancer per-
agent which holds agent-specific state that cannot safely be shared.
This commit introduces our own registry that _is_ thread-safe, and
implements the Builder interface such that we can call gRPC's `Register`
method once, on start-up. It uses the same pattern as our resolver
registry where we use the dial target's host (aka "authority"), which is
unique per-agent, to determine which builder to use.
Prior to this commit, all peer services were transmitted as connect-enabled
as long as a one or more mesh-gateways were healthy. With this change, there
is now a difference between typical services and connect services transmitted
via peering.
A service will be reported as "connect-enabled" as long as any of these
conditions are met:
1. a connect-proxy sidecar is registered for the service name.
2. a connect-native instance of the service is registered.
3. a service resolver / splitter / router is registered for the service name.
4. a terminating gateway has registered the service.
Protobuf Refactoring for Multi-Module Cleanliness
This commit includes the following:
Moves all packages that were within proto/ to proto/private
Rewrites imports to account for the packages being moved
Adds in buf.work.yaml to enable buf workspaces
Names the proto-public buf module so that we can override the Go package imports within proto/buf.yaml
Bumps the buf version dependency to 1.14.0 (I was trying out the version to see if it would get around an issue - it didn't but it also doesn't break things and it seemed best to keep up with the toolchain changes)
Why:
In the future we will need to consume other protobuf dependencies such as the Google HTTP annotations for openapi generation or grpc-gateway usage.
There were some recent changes to have our own ratelimiting annotations.
The two combined were not working when I was trying to use them together (attempting to rebase another branch)
Buf workspaces should be the solution to the problem
Buf workspaces means that each module will have generated Go code that embeds proto file names relative to the proto dir and not the top level repo root.
This resulted in proto file name conflicts in the Go global protobuf type registry.
The solution to that was to add in a private/ directory into the path within the proto/ directory.
That then required rewriting all the imports.
Is this safe?
AFAICT yes
The gRPC wire protocol doesn't seem to care about the proto file names (although the Go grpc code does tack on the proto file name as Metadata in the ServiceDesc)
Other than imports, there were no changes to any generated code as a result of this.

Fix mesh gateways incorrectly matching peer locality.
This fixes an issue where local mesh gateways use an
incorrect address when attempting to forward traffic to a
peered datacenter. Prior to this change it would use the
lan address instead of the wan if the locality matched. This
should never be done for peering, since we must route all
traffic through the remote mesh gateway.
* Fix infinite recursion on InlineCertificateConfigEntry
GetNamespace() + GetMeta() were calling themselves. This change also simplifies by removing nil-checking to match pre-existing config entries

Prior to this PR, servers / agents would panic and crash if an ingress
or api gateway were configured to use a discovery chain that both:
1. Referenced a peered service
2. Had a mesh gateway mode of local
This could occur, because code for handling upstream watches was shared
between both connect-proxy and the gateways. As a short-term fix, this
PR ensures that the maps are always initialized for these gateway services.
This PR also wraps the proxycfg execution and service
registration calls with recover statements to ensure that future issues
like this do not put the server into an unrecoverable state.

Prior to this commit, secondary datacenters could not be initialized
as peering acceptors if ACLs were enabled. This is due to the fact that
internal server-to-server API calls would fail because the management
token was not generated. This PR makes it so that both primary and
secondary datacenters generate their own management token whenever
a leader is elected in their respective clusters.

This endpoint shows total services, connect service instances and
billable service instances in the local datacenter or globally. Billable
instances = total service instances - connect services - consul server instances.
