The available services mechanism does not currently support tempest plugins, as it includes several hardcoded lists within tempest itself (tempest/test.py, tempest/config.py) and within devstack (lib/tempest).

An example of this from tempest/test.py:

    def get_service_list():
        service_list = {
            'compute': CONF.service_available.nova,
            'image': CONF.service_available.glance,
            'baremetal': CONF.service_available.ironic,
            'volume': CONF.service_available.cinder,
            'orchestration': CONF.service_available.heat,
            # NOTE(mtreinish) nova-network will provide networking functionality
            # if neutron isn't available, so always set to True.
            'network': True,
            'identity': True,
            'object_storage': CONF.service_available.swift,
            'dashboard': CONF.service_available.horizon,
            'telemetry': CONF.service_available.ceilometer,
            'data_processing': CONF.service_available.sahara,
            'database': CONF.service_available.trove
        }
        return service_list

We should extend or replace these mechanisms to support plugins.
