GrpcChannel - _methodInfoCache does not Work

[marcprob]

In the class Grpc.Net.Client.GrpcChannel there is a ThreadSafeLookup<IMethod, GrpcMethodInfo> _methodInfoCache.

However, since Grpc.Core.Method does not provide an override for GetHashCode (or Equals), the cache never stores or retrieves entries correctly. This results in _methodInfoCache not caching anything as intended.

Expected behavior:
Grpc.Core.Method should override Equals and GetHashCode so that instances referring to the same method can be matched and cached properly.

Actual behavior:
Each Grpc.Core.Method instance is considered unique, even when referring to the same RPC method, causing unnecessary cache misses.

I can confirm that bug is present. Is there any workaround for that?
