auth: Enhancement for the supported auth methods

- If no auth protocol defined, `cephx` is used by default, it's debatable if
  ceph should abort here or use `cephx` by default, but if `cephx` is used
  in this case it's better to give some warning message.
- ceph has CEPH_AUTH_UNKNOWN auth protocol defined, change to use this
  protocol if the auth method is unknown.
