Description

RPC detailed metrics for any protobuf-based RPC ports are always zero. ProtoOverHadoopRpcEngine needs the same detailed metric logic as in WritableRpcEngine. This is effectively the same change as in HADOOP-8085 except tailored for branch-0.23 which didn't take the full protobuf branch changes that went into branch-2 and trunk.
