GEODE-6781: Switch from deprecated Authenticator to SecurityManager for examples (#528)

* Have the authentication use a SecurityManager vs Authenticator.
* Bash script was stopping servers vs shutdown.
* No reason to destroy the region if we are deleting the data directory.   Wait for process to die before trying to delete the data directories.
