leap_cli: add ability to remove admins
From what I can tell, there is only a 'add-user' option to leap-cli. There should be an easier way to remove users as well. It seems the only way to do this is to rm -rf the users/foo directory and hand-edit the authorized_keys file and then redeploy.
Ideally what would happen:
$ leap rm-user foo removing users/foo removing foo's key(s) from files/ssh/authorized_keys finished - you must run leap deploy to make these changes on the servers $
