Currently compute hosts_client returns Response by removing top key from Response. For example- return service_client.ResponseBody(resp, body['host']) As service clients are in direction to move to Tempest-lib, all service clients should return Response without any truncation. One good example is Resource pagination links which are lost with current way of return value. Resource pagination links are present in parallel (not inside) to top key of Response. This patch makes compute hosts_client to return complete Response body. Implements: blueprint method-return-value-and-move-service-clients-to-lib Change-Id: Ife5bdbbcbdd856ecbce66e8b9c74c70dbb93f077
