For static volume, the user will manually mounts
already existing image as a volume to the application
pods. As its a rbd Image, if the PVC is of type
fileSystem the image will be mapped, formatted
and mounted on the node,
If the user resizes the image on the ceph cluster.
User cannot not automatically resize the filesystem
created on the rbd image. Even if deletes and
recreates the kubernetes objects, the new size
will not be visible on the node.
With this changes During the NodeStageVolumeRequest
the nodeplugin will check the size of the mapped rbd
image on the node using the devicePath. and also
the rbd image size on the ceph cluster.
If the size is not matching it will do the file
system resize on the node as part of the
NodeStageVolumeRequest RPC call.
The user need to do below operation to see new size
* Resize the rbd image in ceph cluster
* Scale down all the application pods using the static
PVC.
* Make sure no application pods which are using the
static PVC is running on a node.
* Scale up all the application pods.
Validate the new size in application pod mounted
volume.

We have many declarations and invocations..etc with long lines which are
very difficult to follow while doing code reading. This address the issues
in 'e2e/staticpvc.go' and 'e2e/snapshot.go' files to restrict the line length
to 120 chars.

In Go 1.13, the fmt.Errorf function supports a new %w verb.
When this verb is present, the error returned by fmt.Errorf
will have an Unwrap method returning the argument of %w,
which must be an error. In all other ways, %w is identical to %v.

We had "ns" as a parameter and then trying to
declare it also as a local variable, which is what
the complaint about "shadowing" refers to.
Issue reported:
shadow: declaration of "ns" shadows declaration at line 57 (govet)

the static check is failing as the replicapool
is used in 3 or more places, we need to define
a variable and use it.

With client-go v1.18.0 there is a change where Signatures on methods
in generated clientsets, dynamic, metadata, and scale clients have been
modified to accept context.Context as a first argument.
Signatures of Create, Update, and Patch methods have been updated to accept
CreateOptions, UpdateOptions and PatchOptions respectively.
Signatures of Delete and DeleteCollection methods now accept DeleteOptions
by value instead of by reference
The framework.RunkubectlInput now accepts namespace as the first parameter
which is also accommodated with this PR.
