To avoid subvolume leaks if the SetAllMetadata
operations fails delete the subvolume.
If any operation fails after creating the subvolume
we will remove the omap as the omap gets
removed we will need to remove the subvolume to
avoid stale resources.

NewContextFrom{Mountpoint,Path} functions use cached
`/proc/self/mountinfo` to find mounted file systems by device ID.
Since we run fscrypt as a library in a long-lived process the cached
information is likely to be stale. Stale entries may map device IDs to
mount points of already destroyed RBDs and fail context creation.
Updating the cache beforehand prevents this.

CephFS does not have a concept of "free inodes", inodes get allocated
on-demand in the filesystem.
This confuses alerting managers that expect a (high) number of free
inodes, and warnings get produced if the number of free inodes is not
high enough. This causes alerts to always get reported for CephFS.
To prevent the false-positive alerts from happening, the
NodeGetVolumeStats procedure for CephFS (and CephNFS) will not contain
inodes in the reply anymore.

To address the problem that snapshot
schedules are triggered for volumes
that are promoted, a dummy image was
disabled/enabled for replication.
This was done as a workaround, because the
promote operation was not triggering
the schedules for the image being promoted.
The bugs related to the same have been fixed in
RBD mirroring functionality and hence the
workaround #2656 can be removed from the code base.
