> Related to HBASE-16138. As of now we currently have no pause between retrying 
> failed region open requests. And with a low maximumAttempt default, we can 
> quickly use up all our regionOpen retries if the server is in a bad state. I 
> added in a ExponentialBackOffPolicy so that we spread out the timing of our 
> open region retries in AssignmentManager. Review board at
