config-neutron: 'external_gateway_info' in router should be a dictionary

[Hampapur Ajay]

Tempest test
tempest.api.network.test_routers.RoutersTest.test_create_show_list_update_delete_router
fails because 'external_gateway_info' is directly the VN uuid instead of dictionary

{u'router': {u'status': u'ACTIVE', u'external_gateway_info': u'98ab1ff2-f092-4d74-a73d-21fc2c4a42da', u'name': u'router--800443694', u'admin_state_up': False, u'tenant_id': u'6aa4f438347842c8b79317f2e475dde3', u'id': u'a4bb2771-eebb-497e-b6a6-b2e35e6a38d5', u'contrail:fq_name': [u'default-domain', u'demo', u'router--800443694']}}
