This commit adds the support for storing the CephFS omap data
in a namespace specified in the ceph-csi-config ConfigMap under
cephFS.radosNamespace field.
If the radosNamespace is not set, the default radosNamespace will
be used i.e, csi.

This commit resolves the govet issue -
`copylocks: call of append copies lock value ... contains sync.Mutex`
Embedding DoNotCopy in a struct is a convention to signal and prevent
shallow copies, as recommended in Go's best practices. This does not
rely on a language feature but is instead a special case within the vet
checker.
For more details, see https://golang.org/issues/8005

instead of adding single volumes to the
group journal, support adding multiple
volumeID's map to the group journal
which is required for RBD as well.

Adjusted method names to not have any
specific things to volumesnapshot as
we want to reuse the same journal for
volumegroup as well.

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.

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.
