Bump golang.org/x/net to 0.12.0
While not necessary to directly address CVE-2023-29406 (which should be
handled by using a patched version of Go when building), an
accompanying change to HTTP/2 error handling does impact agent code.
See https://go-review.googlesource.com/c/net/+/506995 for the HTTP/2
change.
Bump this dependency across our submodules as well for the sake of
potential indirect consumers of `x/net/http`.
TLDR with many modules the versions included in each diverged quite a bit. Attempting to use Go Workspaces produces a bunch of errors.
This commit:
1. Fixes envoy-library-references.sh to work again
2. Ensures we are pulling in go-control-plane@v0.11.0 everywhere (previously it was at that version in some modules and others were much older)
3. Remove one usage of golang/protobuf that caused us to have a direct dependency on it.
4. Remove deprecated usage of the Endpoint field in the grpc resolver.Target struct. The current version of grpc (v1.55.0) has removed that field and recommended replacement with URL.Opaque and calls to the Endpoint() func when needing to consume the previous field.
4. `go work init <all the paths to go.mod files>` && `go work sync`. This syncrhonized versions of dependencies from the main workspace/root module to all submodules
5. Updated .gitignore to ignore the go.work and go.work.sum files. This seems to be standard practice at the moment.
6. Update doc comments in protoc-gen-consul-rate-limit to be go fmt compatible
7. Upgraded makefile infra to perform linting, testing and go mod tidy on all modules in a flexible manner.
8. Updated linter rules to prevent usage of golang/protobuf
9. Updated a leader peering test to account for an extra colon in a grpc error message.
* 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
Our original intention was for projects to consume and generate their
own Go code for these protobuf packages using Buf. While this is still
the best route for many projects, it causes some headaches when using
a library (e.g. consul-server-connection-manager) that pulls in the
same protobuf package as your project, as Go's protobuf implementation
only allows for a package/namespace to be registered once.
In such cases, projects can depend on this Go module instead, as a
single place where these protobuf packages are registered.
