    enable barbican help without authentication

    This fix enables 'barbican help' and 'barbican complete' to
    not need authentication. This commit also enables deferred_help
    so that the following command can be ran:
    'barbican secret list --help' (the help for the
    particular command will be shown).
    The code changes are similar to the python-openstackclient
    usage of the cliff library. The current implementation
    of the barbican client authenticates before checking the type of
    command. This early authentication causes the client
    to fail with 'barbican help'. This code change will
    check if the command requires authentication
    and creates the client.
