IMPALA-9165: Add back hard kill to kill-hbase.sh

The fix for IMPALA-9150 changed kill-hbase.sh to use HBase's
stop-hbase.sh script. Around this time, the GVO timeout issues
started. GVO can reuse machines, so we don't know what state
they may be in. If something failed to kill HBase processes,
the next job would need to be able to kill them even without
access to the last run's files / logs.

This restores the original kill logic to kill-hbase.sh, after
trying a graceful shutdown using HBase's stop-hbase.sh script.
The original kill logic doesn't rely on anything from the
filesystem to know about the existence of processes, so it
would handle machine reuse.

This also changes our Jenkins test scripts to shut down the
minicluster at the end.

Testing:
 - Started with a running minicluster, ran bin/clean.sh,
   then ran testdata/bin/kill-all.sh and verified that the
   java processes were gone
