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.

This commit ensures that parent image is flattened before
creating volume.
- If the data source is a PVC, the underlying image's parent
is flattened(which would be a temp clone or snapshot).
hard & soft limit is reduced by 2 to account for depth that
will be added by temp & final clone.
- If the data source is a Snapshot, the underlying image is
itself flattened.
hard & soft limit is reduced by 1 to account for depth that
will be added by the clone which will be restored from the
snapshot.
Flattening step for resulting PVC image restored from snapshot is removed.
Flattening step for temp clone & final image is removed when pvc clone is
being created.

as per the CSI standard the size is optional parameter,
as we are allowing the clone to a bigger size
today we need to block the clone to a smaller size
as its a have side effects like data corruption etc.
Note:- Even though this check is present in kubernetes
sidecar as CSI is CO independent adding the check
here.

With Amazon STS and kubernetes cluster is configured with
OIDC identity provider, credentials to access Amazon KMS
can be fetched using oidc-token(serviceaccount token).
Each tenant/namespace needs to create a secret with aws region,
role and CMK ARN.
Ceph-CSI will assume the given role with oidc token and access
aws KMS, with given CMK to encrypt/decrypt DEK which will stored
in the image metdata.

Currently, we support
mapOption: "krbd:v1,v2,v3;nbd:v1,v2,v3"
- By omitting `krbd:` or `nbd:`, the option(s) apply to
rbdDefaultMounter which is krbd.
- A user can _override_ the options for a mounter by specifying `krbd:`
or `nbd:`.
mapOption: "v1,v2,v3;nbd:v1,v2,v3"
is effectively the same as the 1st example.
- Sections are split by `;`.
- If users want to specify common options for both `krbd` and `nbd`,
they should mention them twice.
But in case if the krbd or nbd specifc options contian `:` within them,
then the parsing is failing now.

This patch fix the above case where the options itself contain `:`

Please note, if you are using such options which contain `:` delimiter,

Mounts managed by ceph-fuse may get corrupted by e.g. the ceph-fuse process
exiting abruptly, or its parent container being terminated, taking down its
child processes with it.
This commit adds checks to NodeStageVolume and NodePublishVolume procedures
to detect whether a mountpoint in staging_target_path and/or target_path is
corrupted, and remount is performed if corruption is detected.

Refactored a couple of helper functions for easier resue.
* Code for building store.VolumeOptions is factored out into a separate function.
* Changed args of getCredentailsForVolume() and NodeServer.mount() so that
instead of passing in whole csi.NodeStageVolumeRequest, only necessary
properties are passed explicitly. This is to allow these functions to be
called outside of NodeStageVolume() where NodeStageVolumeRequest is not
available.
