> Implement a multi-level priority queue sorted replication policy which plugs into the
replication framework (HBASE-1733). Split incoming logs. Sort outbound edits by priority.
One option is to consider each column family's replication policy tag as an index into a deadline
table for EDF scheduling (http://en.wikipedia.org/wiki/Earliest_deadline_first_scheduling).
