Description
Add an option to `fs subvolume create` command to allow subvolumes to be created in unique RADOS namespaces.
The create_subvol() method already has a parameter `isolate_nspace` that can be set to True to set a RADOS namespace for a subvolume, but the parameter is now always set to False. Make it configurable based on user input.
https://github.com/ceph/ceph/blob/master/src/pybind/mgr/volumes/fs/volume.py#L122
And it'd be useful to display the RADOS namespace of the subvolume in `fs subvolume info`.
use-case:
This is required by manila's CephFS driver that creates subvolumes/shares in unique RADOS namespaces.
