csidriver object can be created on the kubernetes
for below reason.
If a CSI driver creates a CSIDriver object,
Kubernetes users can easily discover the CSI
Drivers installed on their cluster
(simply by issuing kubectl get CSIDriver)

Tenants can have their own ConfigMap that contains connection parameters
to the Vault Service where the PV encyption keys are located. It is
possible for a Tenant to use a different Vault Service than the one
configured by the Storage Admin who deployed Ceph-CSI.
For this, the node-plugin needs to be able to read the ConfigMap from
the Tenants namespace.

if the kms encryption configmap is not mounted
as a volume to the CSI pods, add the code to
read the configuration from the kubernetes. Later
the code to fetch the configmap will be moved to
the new sidecar which is will talk to respective
CO to fetch the encryption configurations.
The k8s configmap uses the standard vault spefic
names to add the configurations. this will be converted
back to the CSI configurations.

This argument in csi-provisioner sidecar allows us to receive pv/pvc
name/namespace metadata in the createVolume() request.
For ex:
csi.storage.k8s.io/pvc/name
csi.storage.k8s.io/pvc/namespace
csi.storage.k8s.io/pv/name
This is a useful information which can be used depend on the use case we
have at our driver. The features like vault token enablement for multi
tenancy, RBD mirroring ..etc can consume this based on the need.

`make image-cephcsi` will fail when Golang is not installed. There is no
strict requirement for Golang to be available, it is only used to gather
the architecture of the OS where the image is built. It is possible to
build the image successfully with `make image-cephcsi GOARCH=amd64`.
In case Golang is not installed, GOARCH can not be detected
automatically. This will cause a failure while installing Golang in the
container image. Because the failure is not very clear, display a
warning in the case the GO_ARCH (from ${GOARCH} in the Makefile) is not
set.

For building a arm64 container image on amd64, it is needed to configure
the system specifically for that. In order to prevent including a amd64
executable in a arm64 image, a check has been added.
When running an arm64 executable on a amd64 system, an error should
occur when cross architecture containers are not supported. This can be
triggered when running `make image-cephcsi GO_ARCH=arm64` on a amd64
system.

When building with go-ceph, there are several dynamically linked

should be caught before publishing/consuming the image.

- avoids encrypting volume second time if it was already encrypted but
no file system created
- avoids unnecessary checks if volume is a mapped device when encryption
was not requested
- prevents resizing encrypted volumes (it is not currently supported)
- prevents creating snapshots from encrypted volumes to prevent attack
on encryption key (security guard until re-encryption of volumes
