hbase_regionserver_shutdown_timeout should be editable any time. Its now only
editable during install.
<display-name>HBase RegionServer shutdown timeout</display-name>
After this number of seconds waiting for graceful stop of HBase Master it will be forced to exit with SIGKILL.
The timeout is introduced because there is a known bug when from time to time HBase RegionServer hangs forever on stop if NN safemode is on.
