Ceph » CephFS

The FS subvolumes library module will be heavily borrowed from ceph_volume_client. It'll be used to provision FS subvolumes (CephFS subdir with a specific layout and quota) and subvolume-groups (parent directories of FS subvolumes), and to perform other subvolume and subvolume-group level operations (snapshot, ls, allow/deny access, etc). The `ceph fs subvolume` and `ceph fs subvolumegroup` set of commands will make use of this library.
