HADOOP-16266. Add more fine-grained processing time metrics to the RPC layer -follow-on patch.

Browse Source 
This follow-on patch to HADOOP-16266 fixes up the problem where logs were being full of
stack traces because the timeout passed down to select was in nanos, whereas the API
expected millis.

Contributed by Erik Krogen.
