HBASE-29644: Refresh_meta triggering compaction on user table

Link to JIRA: https://issues.apache.org/jira/browse/HBASE-29644

Description:
Consider the two cluster setup with one being active and one read replica. If active cluster create a table with FILE based SFT. If you add few rows through active and do flushes to create few Hfiles and then do refresh_meta from read replica its triggering minor compaction. Which should not happen via read replica, it may create inconsitencies because active is not aware of that event.

Cause:
This is happening because we should block the compaction event in ReadOnlyController but we missed adding read only guard to preCompactSelection() function.

Fix:
Add internalReadOnlyGuard to preCompactSelection() in ReadOnlyController
