> HADOOP-10597 added support for RPC congestion control by sending retriable 'server too
busy' exceptions to clients. 
> However every backoff results in a log message. We've seen these log messages slow down
the NameNode.

8020: readAndProcess from client threw exception [org.apache.hadoop.ipc.RetriableException:
Server is too busy.]
> {code}
> We already have a metric that tracks the number of backoff events. This log message adds
nothing useful.
> The IPC Server should also allow services to skip logging certain exception types altogether.
