This PR removes attaching the "Sent." and "Recv." prefixes to the Span Name dependent on the Span Kind. This is the functionality in Java and C++ stackdriver exporters. gRPC-Go's Observability project was running into issues where we would get "Sent.Sent.MethodName" and "Sent.Attempt.MethodName" in the stackdriver backends. gRPC-Go sets the names "Sent.MethodName" and "Attempt.MethodName", and this is what we want displayed in the backend.
