[RFE] API to list nodes using the same driver

[Kan]

For nodes, there are multiple drivers can be managed in conductor, sometimes users want to check out the nodes that belong to the same driver group.
But now the driver info of each node can only be got by 'list --detail', 'list --fields driver' or 'show' command, which misses the filter to get the results using one command.
This functionality needs add a new argument in client and a new filter in api.
