2943555904 cephfs: fix omap deletion in DeleteSnapshot
the omap is stored with the requested
snapshot name not with the subvolume
snapshotname. This fix uses the correct
snapshot request name to cleanup the omap
once the subvolume snapshot is deleted.

fixes: #2832

ef14ea7723 cephfs: resize cloned, restored volume if required
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.

12e8e46bcf revert: remove explicit size setting of cloned volume
The ceph changes  are done on the both server and the
client side this change is not enough for remove
setting the size of cloned volumes.
this caused the regression like #2719 #2720 #2721 #2722.

This reverts commit 3565a342d5.

b1ef842640 cleanup: move core functions to core pkg
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.

df2d9548ae cephfs: no need to check for zero volume size
At present there is a 'todo' to check for zero volume size
in the createVolume request which in unwanted, ie the pvc
creation with size 0 fail from the kubernetes api validation itself:

For ex:

```
..spec.resources[storage]: Invalid value: "0": must be greater than zero```
```
so we dont need any extra check in the controller server

247795517f cephfs: remove explicit size setting of cloned volume
CephFS csi driver explictly set the size of the cloned volume
to the size of parent volume as cephfs mgr was lacking this
functionality previously. However it has been addressed in cephfs
so we dont need explicit size setting.

Ref#https://tracker.ceph.com/issues/46163

6d00b39886 cleanup: move log functions to new internal/util/log package
Moving the log functions into its own internal/util/log package makes it
possible to split out the humongous internal/util packages in further
smaller pieces. This reduces the inter-dependencies between utility
functions and components, preventing circular dependencies which are not
allowed in Go.
