Currently the "get_minimum_version_all_cells" functions in service runs sequentially and this affects the performance in case of large deployments (running a lot of cells) : https://github.com/openstack/nova/blob/stable/pike/nova/objects/service.py#L440
So it would be nice to use the scatter_gather_all_cells function to do this operation in parallel. |

Also apart from the scaling point of view, in case connection to a particular cell fails, it would be nice to have sentinels returned which is done by the scatter_gather_all_cells. This helps when a DB is down |
