> Priority: Critical

> Similar to HBASE-1476 and HBASE-2646 which are for compactions, but do this for flushes.
> Flushing when we hit the normal flush size is a low priority flush. Other types of flushes (heap pressure, blocking client requests, etc) are high priority.
> Should have a tunable number of concurrent flushes.
> Will use the {{HBaseExecutorService}} and {{HBaseEventHandler}} introduced from master/zk changes.
