97cb1b6672 fscrypt: Update mount info before create context
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.

b7703faf37 util: make inode metrics optional in FilesystemNodeGetVolumeStats()
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.

71e5b3f922 rbd: remove dummy image workaround
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.
