Title: Tweaks to improve user experience

This was developed alongside `jrd-security-output` in `riak_core`, but the changes are entirely independent, so the branches can be merged separately or not at all.

* Indicate the security status after an attempt to change it
* Prevent an ugly RPC error if an admin accidentally supplies extra arguments to `print-user` or `print-group`
