3a1d55db16 rbd: do not execute rbd sparsify when volume is in use
This commit makes sure sparsify() is not run when rbd
image is in use.
Running rbd sparsify with workload doing io and too
frequently is not desirable.
When a image is in use fstrim is run and sparsify will
be run only when image is not mapped.

0ec6e10bf2 util: Limit cryptsetup PBKDF memory usage
By default, `cryptsetup luksFormat` uses Argon2i as Password-Based Key
Derivation Function (PBKDF), which not only has a CPU cost, but also a memory
cost (to make brute-force attacks harder).

The memory cost is based on the available system memory by default, which in
the context of Ceph CSI can be a problem for two reasons:

1. Pods can have a memory limit (much lower that the memory available on the
   node, usually) which isn't taken into account by `cryptsetup`, so it can get
   OOM-killed when formating a new volume;
2. The amount of memory that was used during `cryptsetup luksFormat` will then
   be needed for `cryptsetup luksOpen`, so if the volume was formated on a node
   with a lot of memory, but then needs to be opened on a different node with
   less memory, `cryptsetup` will get OOM-killed.

This commit sets the PBKDF memory limit to a fixed value to ensure consistent
memory usage regardless of the specifications of the nodes where the volume
happens to be formatted in the first place.

The limit is set to a relatively low value (32 MiB) so that the `csi-rbdplugin`
container in the `nodeplugin` pod doesn't require an extravagantly high memory
limit in order to format/open volumes (particularly with operations happening
in parallel), while at the same time not being so low as to render it
completely pointless.

e54a97ba85 rbd: discover if StagingTargetPath in NodeExpandVolume
The StagingTargetPath is an optional entry in
NodeExpandVolumeRequest, We cannot expect it to be
set always and at the same time cephcsi depended
on the StaingTargetPath to retrieve some metadata
information.

This commit will check all the mount ref and identifies
the stagingTargetPath by checking the image-meta.json
file exists and this is a costly operation as we need to
loop through all the mounts and check image-meta.json
in each mount but this is happens only if the
StaingTargetPath is not set in the NodeExpandVolumeRequest

f7796081d3 cephfs: skip expand for BackingSnapshot volume
We should not call ExpandVolume for the BackingSnapshot
subvolume as there wont be any real subvolume created for
it and even if we call it the ExpandVolume will fail
fail as there is no real subvolume exists.

This commits fixes by adjusting the `if` check to ensure
that ExpandVolume will only be called either the
VolumeRequest is to create from a snapshot or volume
and BackingSnapshot is not true.

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.
