Protobuf Refactoring for Multi-Module Cleanliness (#16302)
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.

Protobuf Modernization (#15949)
* Protobuf Modernization

Remove direct usage of golang/protobuf in favor of google.golang.org/protobuf

Marshallers (protobuf and json) needed some changes to account for different APIs.

Moved to using the google.golang.org/protobuf/types/known/* for the well known types including replacing some custom Struct manipulation with whats available in the structpb well known type package.

This also updates our devtools script to install protoc-gen-go from the right location so that files it generates conform to the correct interfaces.

* Fix go-mod-tidy make target to work on all modules

grpc: `protoc` plugin for generating gRPC rate limit specifications (#15564)
Adds automation for generating the map of `gRPC Method Name → Rate Limit Type`
used by the middleware introduced in #15550, and will ensure we don't forget
to add new endpoints.

Engineers must annotate their RPCs in the proto file like so:

```
rpc Foo(FooRequest) returns (FooResponse) {
  option (consul.internal.ratelimit.spec) = {
    operation_type: READ,
  };
}
```

When they run `make proto` a protoc plugin `protoc-gen-consul-rate-limit` will
be installed that writes rate-limit specs as a JSON array to a file called
`.ratelimit.tmp` (one per protobuf package/directory).

After running Buf, `make proto` will execute a post-process script that will
ingest all of the `.ratelimit.tmp` files and generate a Go file containing the
mappings in the `agent/grpc-middleware` package. In the enterprise repository,
it will write an additional file with the enterprise-only endpoints.

If an engineer forgets to add the annotation to a new RPC, the plugin will
return an error like so:

```
RPC Foo is missing rate-limit specification, fix it with:

	import "proto-public/annotations/ratelimit/ratelimit.proto";

	service Bar {
	  rpc Foo(...) returns (...) {
	    option (hashicorp.consul.internal.ratelimit.spec) = {
	      operation_type: OPERATION_READ | OPERATION_WRITE | OPERATION_EXEMPT,
	    };
	  }
	}
```

In the future, this annotation can be extended to support rate-limit
category (e.g. KV vs Catalog) and to determine the retry policy.

adding config for request_limits (#15531)
* server: add placeholder glue for rate limit handler

This commit adds a no-op implementation of the rate-limit handler and
adds it to the `consul.Server` struct and setup code.

This allows us to start working on the net/rpc and gRPC interceptors and
config logic.

grpc: add rate-limiting middleware (#15550)
Implements the gRPC middleware for rate-limiting as a tap.ServerInHandle
function (executed before the request is unmarshaled).

Mappings between gRPC methods and their operation type are generated by
a protoc plugin introduced by #15564.

grpc: rename public/private directories to external/internal (#13721)
Previously, public referred to gRPC services that are both exposed on
the dedicated gRPC port and have their definitions in the proto-public
directory (so were considered usable by 3rd parties). Whereas private
referred to services on the multiplexed server port that are only usable
by agents and other servers.

Now, we're splitting these definitions, such that external/internal
refers to the port and public/private refers to whether they can be used
by 3rd parties.

This is necessary because the peering replication API needs to be
exposed on the dedicated port, but is not (yet) suitable for use by 3rd
parties.
