There has been some confusion about using different variables for the
InstanceID of the RBD-driver. By removing the global variable
CSIInstanceID, there should be no confusion anymore what variable to
use.

There is no release for sigs.k8s.io/controller-runtime that supports
Kubernetes v1.27. The main branch has all the required modifications, so
we can use that for the time being.

As we added support to set the metadata on the rbd images created for
the PVC and volume snapshot, by default metadata is set on all the images.
As we have seen we are hitting issues#2327 a lot of times with this,
we start to leave a lot of stale images. Currently, we rely on
`--extra-create-metadata=true` to decide to set the metadata or not,
we cannot set this option to false to disable setting metadata because we
use this for encryption too.
This changes is to provide an option to disable setting the image
metadata when starting cephcsi.

Example if a PVC was delete by setting `persistentVolumeReclaimPolicy` as
`Retain` on PV, and PV is reattached to a new PVC, we make sure to update
PV/PVC image metadata on a PV reattach.

Below are the 3 different cases where we need
the PVC namespace for encryption
* CreateVolume:- Read the namespace from the
createVolume parameters and store it in the omap
* NodeStage:- Read the namespace from the omap
not from the volumeContext
* Regenerate:- Read the pvc namespace from the claimRef
not from the volumeAttributes.

we have added clusterID mapping to identify the volumes
in case of a failover in Disaster recovery in #1946.
with #2314 we are moving to a configuration in
configmap for clusterID and poolID mapping.
and with #2314 we have all the required information
to identify the image mappings.
This commit removes the workaround implementation done
in #1946.

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.

ContollerManager had a typo in it, and if we correct it,
linter will fail and suggest not to use controller.ControllerManager
as the interface name and package name is redundant, keeping manager
as the interface name which is the practice and also address the
linter issues.

In the case of the Async DR, the volumeID will
not be the same if the clusterID or the PoolID
is different, With Earlier implementation, it
is expected that the new volumeID mapping is
stored in the rados omap pool. In the case of the
ControllerExpand or the DeleteVolume Request,
the only volumeID will be sent it's not possible
to find the corresponding poolID in the new cluster.
With This Change, it works as below
The csi-rbdplugin-controller will watch for the PV
objects, when there are any PV objects created it
will check the omap already exists, If the omap doesn't
exist it will generate the new volumeID and it checks for
the volumeID mapping entry in the PV annotation, if the
mapping does not exist, it will add the new entry
to the PV annotation.
The cephcsi will check for the PV annotations if the
omap does not exist if the mapping exists in the PV
annotation, it will use the new volumeID for further
operations.

In the case of Disaster Recovery failover, the
user expected to create the static PVC's. We have
planned not to go with the PVC name and namespace
for many reasons (as in kubernetes it's planned to
support PVC transfer to a new namespace with a
different name and with new features coming in
like data populator etc). For now, we are
planning to go with static PVC's to support
async mirroring.
During Async mirroring only the RBD images are
mirrored to the secondary site, and when the
user creates the static PVC's on the failover
we need to regenerate the omap data. The
volumeHandler in PV spec is an encoded string
which contains clusterID and poolID and image UUID,
The clusterID and poolID won't remain same on both
the clusters, for that cephcsi need to generate the
new volume handler and its to create a mapping
between new volume handler and old volume handler
with that whenever cephcsi gets csi requests it
check if the mapping exists it will pull the new
volume handler and continues other operations.
The new controller watches for the PVs created,
It checks if the omap exists if it doesn't it
will regenerate the entire omap data.
