Ceph

When trying to resetting a client's permissions I've tried to use the 'ceph auth add' command, and it failed. When searched for this scenario I've found online the option of 'ceph auth caps'.

currently the CLI menu show:
auth print_key <entity>
auth print-key <entity>
auth export {<entity>}
auth get-key <entity>
auth get <entity>
auth list
auth import
auth add <entity> {<caps> [<caps>...]}
auth get-or-create-key <entity> {<caps> [<caps>...]}
auth get-or-create <entity> {<caps> [<caps>...]}
