Develop a mechanism to create, update or delete users in the cluster.

Additional context

Would be nice to have vars that supports changing the default admin password (cassandra/casssandra)

@frippe75 will take a look, but isn't the admin password set in the configuration file? We currently keep that free form for user flexibility. That would be compromised if we started having specific configuration variables set as arguments.
