This argument in csi-snapshotter sidecar allows us to receive
snapshot-name/snapshot-namespace/snapshotcontent-name metadata in the
CreateSnapshot() request.
For ex:
csi.storage.k8s.io/volumesnapshot/name
csi.storage.k8s.io/volumesnapshot/namespace
csi.storage.k8s.io/volumesnapshotcontent/name
This is a useful information which can be used depend on the use case we
have at our driver. The features like adding metadata to snapshot image
can consume this based on the need.

Make sure to set metadata when image exist, i.e. if the provisioner pod
is restarted while createVolume is in progress, say it created the image
but didn't yet set the metadata.

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.

The `ceph nfs export ...` commands have changed in recent Ceph releases.
Use the most recent command as a default, fall back to the older command
when an error is reported.

Increase the timeout to 2 minutes to give enough time
for rollback to complete.
As rollback is performed by the force-promote command it,
at times, may take more than a minute
(based on dirty blocks that need to be rolled
back approximately) to rollback.
The added extra 1 minute is useful though to avoid
multiple calls to complete the rollback and in
extremely corner cases to avoid failures in the
first instance of the call when the mirror watcher
is not yet removed (post scaling down the
RBD mirror instance)

NFSVolume instances are short lived, they only extist for a certain gRPC
procedure. It is easier to store the calling Context in the NFSVolume
struct, than to pass it to some of the functions that require it.

These NFS Controller and Identity servers are the base for the new
provisioner. The functionality is currently extremely limited, follow-up
PRs will implement various CSI procedures.
CreateVolume is implemented with the bare minimum. This makes it
possible to create a volume, and mount it with the
kubernetes-csi/csi-driver-nfs NodePlugin.
DeleteVolume unexports the volume from the Ceph managed NFS-Ganesha
service. In case the Ceph cluster provides multiple NFS-Ganesha
deployments, things might not work as expected. This is going to be
addressed in follow-up improvements.
Lots of TODO comments need to be resolved before this can be declared
"production ready". Unit- and e2e-tests are missing as well.

The API is extended for generation of the NFS CSIDriver object. The
YAML file under deploy/ was created by `yamlgen`.
The contents of the csidriver.yaml file is heavily based on the upstream
CSIDriver from the Kubernetes csi-driver-nfs project.
Because ./tools/yamlgen uses the API, it gets copied under vendor/ .
This causes two copies of the API to be included in the repository, but
that can not be prevented, it seems.

RT, reference tracker, is key-based implementation of a reference counter.
Unlike an integer-based counter, RT counts references by tracking unique
keys. This allows accounting in situations where idempotency must be
preserved. It guarantees there will be no duplicit increments or decrements
of the counter.

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.
