By returning a connected rbdVolume in parseVolCreateRequest(), the
CreateVolume() function can be simplified a little. There is no need to
call the additional Connect() and detect failures with it.

Not all snapshot objects are free'd correctly after they were allocated.
It is possible that some connections to the Ceph cluster were never
closed. This does not need to be a noticeable problem, as connections
are re-used where possible, but it isn't clean either.

Just like GenVolFromVolID() the genSnapFromSnapID() function can return
a snapshot. There is no need to allocated an empty snapshot and pass
that to the genSnapFromSnapID() function.

previously, it was a requirement to have attacher sidecar for CSI
drivers and there had an implementation of dummy mode of operation.
However skipAttach implementation has been stabilized and the dummy
mode of operation is going to be removed from the external-attacher.
Considering this driver work on volumeattachment objects for NBD driver
use cases, we have to implement dummy controllerpublish and unpublish
and thus keep supporting our operations even in absence of dummy mode
of operation in the sidecar.
This commit make a NOOP controller publish and unpublish for RBD driver.
CephFS driver does not require attacher and it has already been made free
from the attachment operations.

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.

* CreateVolume:- Read the namespace from the

* NodeStage:- Read the namespace from the omap

* 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.

SINGLE_NODE_WRITER capability ambiguity has been fixed in csi spec v1.5
which allows the SP drivers to declare more granular WRITE capability in form
of SINGLE_NODE_SINGLE_WRITER or SINGLE_NODE_MULTI_WRITER.
These are not really new capabilities rather capabilities introduced to
get the desired functionality from CO side based on the capabilities SP
driver support for various CSI operations, this new capabilities also help
to address new access mode RWOP (readwriteoncepod).
This commit adds a helper function which identity the request is of
multiwriter mode and also validates whether it is filesystem mode or
block mode. Based on the inspection it fails to allow multi write
requests for filesystem mode and only allow multi write request against
block mode.
This commit also adds unit tests for isMultiWriterBlock function which
validates various accesstypes and accessmodes.
