[csharp proto plugin] Apply Obsolete attribute to deprecated services…
… and methods in C# generated code (grpc#32414) Apply Obsolete attribute to deprecated services and methods in C# generated code Fix for grpc#28597 - Deprecated support for enums and enum values is already fixed by protocolbuffers/protobuf#10520 but this is not yet released. It is fixed in Protocol Buffers v22.0-rc1 but the gRPC repo currently has 21.12 as the protocol buffers submodule. - Deprecated support for messages and fields already exists in the protocol buffers compiler. The fix in this PR adds `Obsolete` attribute to classes and methods for deprecated services and methods within services. e.g. ``` service Greeter { option deprecated=true; // service level deprecated // Sends a greeting rpc SayHello (HelloRequest) returns (HelloReply) { option deprecated=true; // method level deprecated } } ``` I couldn't find any protocol buffers plugin tests to update. Tested locally.
