    Description

      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.
