Connection timeouts to nodemanagers are retried at multiple levels

      Description

      The IPC layer will retry connection timeouts automatically (see Client.java), but we are also retrying them with YARN's RetryPolicy put in place when the NM proxy is created. This causes a two-level retry mechanism where the IPC layer has already retried quite a few times (45 by default) for each YARN RetryPolicy error that is retried. The end result is that NM clients can wait a very, very long time for the connection to finally fail.
