    CLI Examples:
        salt '*' acl.delfacl user myuser /tmp/house/kitchen
        salt '*' acl.delfacl default:group mygroup /tmp/house/kitchen
        salt '*' acl.delfacl d:u myuser /tmp/house/kitchen

        salt '*' acl.delfacl user myuser /tmp/house/kitchen recursive=True
'acl.getfacl:'
    Return (extremely verbose) map of FACLs on specified file(s)
    CLI Examples:
        salt '*' acl.getfacl /tmp/house/kitchen
