The "slices" package has been introduced in Go 1.21 and can be used
instead of the Kubernetes package that will be replaced by the standard
package at one point too.

Added unit test for
validateVolumeGroupSnapshotRequest API which
validates the input VolumeGroupSnapshotRequest
request
Signed-off-by: Madhu Rajanna <madhupr007@gmail.com>
implemented DeleteVolumeGroupSnapshot RPC which
does below operations
* Basic request validation
* Get the snapshotId's and volumeId's
mapping reserved for the UUID
* Delete snapshot and remove its mapping
from the omap
* Repeat above steps until all the mapping
are removed
* Remove the reserved uuid from the omap
* Reset the filesystem quiesce, This might be
required as cephfs doesnt provide any options to
remove the quiesce, if we get any request with same
ID again we can reuse the quiesce API for same set-id
* Return success if the received error is
Pool not found or key not found.

implemented CreateVolumeGroupSnapshot RPC which
does below operations
* Basic request validation
* Reserve the UUID for the group name
* Quiesce the filesystem for all the subvolumes
from the input volumeId's
* Take the snapshot for all the input volumeId's
* Add the mapping between volumeId's and snapshot
Id's in omap
* Release the quiesce for the filesystem for
all the subvolumes from the input volumeId's
Undo all the operations if anything fails.

volumegroup.go holders all the helpers
to extra the group details from the request
and also to extra group details from the
groupID.
This also provide helpers to reserve group
for the request Name and also an undo function
incase if somethings goes wrong and we need to
cleanup the reserved omap entries.

The only encoding version that exists is `1`. There is no need to have
multiple constants for that version across different packages. Because
there is only one version, `GenerateVolID()` does not really require it,
and it can use a default version.
If there is a need in the future to support an other encoding version,
this can be revisited with a cleaner solution.

This commit makes use of crush location labels from node
labels to supply `crush_location` and `read_from_replica=localize`
options during mount. Using these options, cephfs
will be able to redirect reads to the closest OSD,
improving performance.

Implemented the capability to include kernel mount options and
fuse mount options for individual clusters within the ceph-csi-config
ConfigMap.This allows users to configure the kernel/fuse mount options
for each cluster separately. The mount options specified in the ConfigMap
will supersede those provided via command line arguments.

Multiple go-routines may simultaneously check for a clusterID's
presence in clusterAdditionalInfo and create an entry if it is
absent. This set of operation needs to be serialized.
Therefore, this commit safeguards clusterAdditionalInfo map

Add support to create RWX clone from the
ROX clone, in ceph no subvolume clone is
created when ROX clone is created from a
snapshot just a internal ref counter is
added. This PR allows creating a RWX clone
from a ROX clone which allows users to create
RW copy of PVC where cephcsi will identify
the snapshot created for the ROX volume and
creates a subvolume from the CephFS snapshot.

Set VolumeOptions.Pool parameter to empty for Snapshot-backed volumes.
This Pool parameter is optional and only used as 'pool-layout' parameter
during subvolume and subvolume clone create request in cephcsi
and not used for Snapshot-backed volume at all.
It is not saved anywhere for use in subsequent operations after create too.
Therefore, We can set it to empty and not error out.

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.
