    Updated default fernet key usage

    This change makes the use of fernet tokens production ready. The changes are
    as follows:
      * Ensures that the keys are rotated on every playbook execution
      * Removes the need to sync keys back to a deployment host when distributing
        them to other keystone hosts.
      * Creates an autonomous key rotation process that can rotate on the following
        intervals [reboot, yearly, annually, monthly, weekly, daily, hourly] to all
        hosts from any keystone fernet host.
      * Fixes the section in `keystone.conf` which was named "fernet_key" instead
        of "fernet_token".
