> ReplicationQueuesHBaseImpl will abort the server if any of its HBase Table writes/reads
fails. We should figure out a reasonable retry limit and pause duration for these operations.
> As of now the timeouts look like: 
> Table initialization:
> 240 retries
> 1 minute pause (because the Master may not be initialized yet, createTable retries are
immediately rejected by PleaseHoldException, so we should sleep in between RPC requests)
> 1 minute RPC timeouts
> Total: At minimum 2 hours of retries
> Normal Replication Table operations:
> 240 retries
> 100 millis pause (because we assume the cluster is in a more stable state, we assume
most exceptions will be RPC timeouts, so I am using the standard RPC pause)
> 1 minute RPC timeouts
> Total: Assuming operations fail because of RPC timeouts, a minimum of 2 hours of retries.
With just pauses we only have 24 seconds. 
> All of these timeouts are configurable too though.
