Review request for hbase.


Summary
-------

This patch includes the first three sub-tasks of HBASE-50:
1. Start and monitor the creation of snapshot via ZooKeeper
2. Create snapshot of an HBase table
3. Some existing functions of HBase are modified to support snapshot

Currently snapshots can be created as expected, but can not be restored or deleted yet


This addresses bug HBASE-50.
