Amit Patel updated HBASE-18539:
-------------------------------
    Description: 
After removing the use of the master's system timestamp for meta updates in 
[HBASE-18328|https://issues.apache.org/jira/browse/HBASE-18328] and now that we 
pass the timestamps during region open/close in 
[HBASE-18395|https://issues.apache.org/jira/browse/HBASE-18395], we can also 
remove all legacy usages of masterSystemTime.

This was initially introduced in 
[HBASE-13709|https://issues.apache.org/jira/browse/HBASE-13709] to send the 
master's current system time during an open region RPC to fix a case where 
certain meta table updates could be eclipsed in very rare circumstances.
