Cleanup proto rules and point to the source of truth

[aignas]

They have been moved to https://github.com/protocolbuffers/protobuf

Not sure who would be the best person to reach out about the status of wether the proto rules outside rules_python are useable already.

I think @alexeagle @comius were working on this? Last I remember, we were waiting for a protobuf release of something before we could switch rules_python to switch to loading them and mark them as deprecated.

I have not seen a migration plan for that. I don't think it's a wise plan to remove these from rules_python at this point. In fact much of the ecosystem has already moved off of the protobuf repo, now that the toolchain flag allows it.

I think I must be confused as to what is the ruleset that should be used for protobuf python library - is it not the py_proto_library from the protobuff repo that should be used instead of the py_proto_library in our repo? What is the maintained rule that people should be advised to use? I thought that it was definitely not py_proto_library from rules_python but not sure about the replacement.

I find it confusing as well. The recent changes are anonymous and have no context or indication of what they are doing:

I guess then it means that we'll just continue having the api as is and we leave the removal for 2.0.

This is the first I hear of a plan to deprecate py_proto_library in rules_python in favor of something in protobuf. Is there an issue or doc with more context?

[aignas]

#1933 was the first time I heard of desire to do something like this.

@comius could you provide some clarity on what the plan is? If even the rules_python maintainers seem unsure, there's no hope for regular users like myself!
