Based on experience with the new gRPC staging deployment. gRPC generates `FullMethod` names such as `-ServiceName-MethodName` which can be confusing. For client calls to a service we actually want something formatted like `ServiceName-MethodName` and for server requests we want just `MethodName`.
This PR adds a method to clean up the `FullMethod` names returned by gRPC and formats them the way we expect.
Fixes#1880.
Updates google.golang.org/grpc and github.com/jmhodges/clock, both test suites pass. A few of the gRPC interfaces changed so this also fixes those breakages.
Adds a server side unary RPC interceptor which includes basic stats. We could also use this to add a server request ID to the context.Context to identify the call through the system, but really I'd rather do that on the client side before the RPC is sent which requires the client interceptor implementation upstream. Also updates google.golang.org/grpc.
Updates #1880.
