ACCUMULO-2621 Add delay to Shutdown step of continuous randomwalk, update README

The Concurrent.xml randomwalk module can shut down and restart the Accumulo cluster during
the test. This commit adds a 10 second delay after shutdown, to give the master plenty of
time to exit before the test attempts to start it up again.

Also, it is essential that the walker(s) running the test have passwordless SSH access to
the cluster to run $ACCUMULO_HOME/bin/start-all.sh. Otherwise, the masters will not restart
and the test will eventually get stuck. The randomwalk README.md now has information about
that.

+Module-Specific Configuration
+-----------------------------
+
+The user accounts for walkers that run the Concurrent.xml module must have
+password-less SSH access to the entire Accumulo cluster, so that they may run
+`$ACCUMULO_HOME/bin/start-all.sh`. Note that this is not the same script as the
+one that starts random walkers; it is the script to start up an Accumulo
+cluster. You can test that access is in place by running
+`$ACCUMULO_HOME/bin/start-all.sh` from the command line of each walker account.
+
+The above access is also needed for any modules that include Concurrent.xml,
+e.g., ShortClean.xml, LongClean.xml.
