Description

Similar to writing flush events to WAL (HBASE-11511) and compaction events to WAL (HBASE-2231), we should write region open and close events to WAL.

This is especially important for secondary region replicas, since we can use this information to pick up primary regions' files from secondary replicas.

However, we may need this for regular inter cluster replication as well, see issues HBASE-10343 and HBASE-9465.

A design doc for secondary replica replication can be found at HBASE-11183.
