Subject Review Request: Cleanup of RIT timeouts and server shutdown handling

Review request for hbase and stack.


Does cleanup of RIT timeouts according to document in progress.  Still finishing document
but I'd like to get this patch tested before finalizing it.

Also found some strange stuff in server shutdown handling that could have easily led to some
double assignment issues that stack was seeing.

This addresses bug HBASE-3181.

Working on tests now.  This definitely changes some behavior that is tested in the new TestMasterFailover
so need to figure if the test should change or whether we need to handle things like CLOSING.
 Maybe let it timeout a few times?
