stack can not be deleted: EndpointNotFound: public endpoint for messaging service in RegionOne region not found

[huangtianhua]

no zaqar service installed
1. create a stack with a nova server, and user_data_format=SOFTWARE_CONFIG, software_config_transport=ZAQAR_MESSAGE
2. the stack create failed, because there is no zaqar endpoint, an exception (EndpointNotFound: public endpoint for messaging service in RegionOne region not found) raised when populate the deployments metadata for server resource,
so the stack is set to CREATE_FAILED, ----it's ok.
3. then I try to delete the stack, but the stack can't be deleted, the same error happened: EndpointNotFound: public endpoint for messaging service in RegionOne region not found. ---- it's incorrect.

    Don't store rsrc_data before zaqar queue created

    Store rsrc_data 'metadata_queue_id' after zaqar queue
    created, to avoid unnecessary queue delete calling when
    delete nova server.
