    Add ``--group`` option to the ``command list`` command to filter the
    commands by group name: ``openstack command list --group volume`` will
    list all Volume commands for the selected API version.  Use
    ``--os-XXXX-api-version`` to select a specific API version for the desired APIs.

    This provides an alternative to searching help output to list the comamnds
    available for specific APIs.  Note that the ``--group`` argument is used as
    a simple substring search in the Command Group column.
