Multiple go-routines may simultaneously create the
subVolumeGroupCreated map or write into it
for a particular group.
This commit safeguards subVolumeGroupCreated map
from concurrent creation/writes while allowing for multiple
readers.

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.

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

In a cluster we can have multiple filesystem
for that we need to have a map of
subvolumegroups to check filesystem is created
nor not.

`--setmetadata` is false by default, honoring it
will keep the metadata disabled by default

This change helps read the cluster name from the cmdline args,
the provisioner will set the same on the subvolume.

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.

This commits refactors the cephfs core
functions with interfaces. This helps in
better code structuring and writing the
unit test cases.

Currently, as a workaround, we are calling
the resize volume on the cloned, restore volumes
to adjust the cloned, restored volumes.
With this fix, we are calling the resize volume
only if there is a size mismatch with requested
and the volume from which the new volume needs
to be created.

as we are refractoring the cephfs code,
Moving all the core functions to a new folder
/pkg called core. This will make things easier
to implement. For now onwards all the core
functionalities will be added to the core
package.
