82f1323af4 cephfs: safeguard localClusterState struct from race conditions
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
from concurrent writes with a mutex to prevent the above problem.

76064d8e34 cephfs: retry subvolumegroup creation
Incase the  subvolumegroup is deleted
and recreated we need to restart the
cephcsi provisioner pod to clear cache
that cephcsi maintains. With this PR
if cephcsi sees NotFound error duing
subvolume creation it will reset the cache
for that filesystem so that in next RPC
call cephcsi will try to create the
subvolumegroup again

1856647506 cephfs: go with default permissions while creating subvolumes
While creating subvolumes, CephFS driver set the mode to `777`
and pass it along to go ceph apis which cause the subvolume
permission to be on 777, however if we create a subvolume
directly in the ceph cluster, the default permission bits are
set which is 755 for the subvolume. This commit try to stick
to the default behaviour even while creating the subvolume.

This also means that we can work with fsgrouppolicy set to
`File` in csiDriver object which is also addressed in this commit.

a1ed6207f6 cephfs: report detailed error message on clone failure
go-ceph provides a new GetFailure() method to retrieve details errors
when cloning failed. This is now included in the `cephFSCloneState`
struct, which was a simple string before.

While modifying the `cephFSCloneState` struct, the constants have been
removed, as go-ceph provides them as well.

to adjust the cloned, restored volumes.
With this fix, we are calling the resize volume
only if there is a size mismatch with requested

to be created.
