NMProxy should retry on NMNotYetReadyException.

RM assigns a container on node N to an app A. > 2. Node N is restarted > 3. A tries to launch container on node N. > 3 could lead to an NMNotYetReadyException depending on whether NM N has > registered with the RM. In MR, this is considered a task attempt failure. A > few of these could lead to a task/job failure. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
