Most consumers of util.ExecCommand() need to convert the returned []byte
format of stdout and/or stderr to string. By having util.ExecCommand()
return strings instead, the code gets a little simpler.
A few commands return JSON that needs to be parsed. These commands will
be replaced by go-ceph implementations later on. For now, convert the
strings back to []byte when needed.

All calls to util.ExecCommand() now pass the context.Context. In some
cases this is not possible or needed, and util.ExecCommand() will not
log the command.
This should make debugging easier when command executions fail.

Current versions of the mkfs.xfs binary enable reflink support by
default. This causes problems on systems where the kernel does not
support this feature. When the kernel the feature does not support, but
the filesystem has it enabled, the following error is logged in `dmesg`:
XFS: Superblock has unknown read-only compatible features (0x4) enabled
Introduce a check to see if mkfs.xfs supports the `-m reflink=` option.
In case it does, pass `-m reflink=0` while creating the filesystem.
The check is executed once during the first XFS filesystem creation. The
result of the check is cached until the nodeserver restarts.

The sentinel error code had additional fields in the errors, that are
used nowhere. This leads to unneccesarily complicated code. This
change replaces the sentinel errors in utils with standard errors
created with errors.New() and adds a simple JoinErrors() function to
be able to combine sentinel errors from different code tiers.

In rbd E2E testing,we need to create snap and clone
as parallel operation.
This helps us to insure that functionality works when
we have parallel delete and create operations and also
it helps to catch bugs when we get parallel requests.

Take operation locks on the resources before operating

In some ceph version if the subvolume is not present, the
ceph returns doesnot exists and in some version not found

By only checking Error ENOENT: for doesnot exist seems good.
even if some error message changes in ceph ceph-csi wont get
any issue.

Added support for RBD PVC to PVC cloning, below
commands are executed to create a PVC-PVC clone from
RBD side.
* Check the depth(n) of the cloned image if n>=(hard limit -2)
or ((soft limit-2) Add a task to flatten the image and return
about (to avoid image leak) **Note** will try to flatten the
temp clone image in the chain if available
* Reserve the key and values in omap (this will help us to
avoid the leak as it's not reserved earlier as we have returned
ABORT (the request may not come back))
* Create a snapshot of rbd image
* Clone the snapshot (temp clone)
* Delete the snapshot
* Snapshot the temp clone
* Clone the snapshot (final clone)
* Delete the snapshot
```bash
1) check the image depth of the parent image if flatten required
add a task to flatten image and return ABORT to avoid leak
(hardlimit-2 and softlimit-2 check will be done)
2) Reserve omap keys
2) rbd snap create <RBD image for src k8s volume>@<random snap name>
3) rbd clone --rbd-default-clone-format 2 --image-feature
layering,deep-flatten <RBD image for src k8s volume>@<random snap>
<RBD image for temporary snap image>
4) rbd snap rm <RBD image for src k8s volume>@<random snap name>
5) rbd snap create <cloned RBD image created in snapshot process>@<random snap name>
6) rbd clone --rbd-default-clone-format 2 --image-feature <k8s dst vol config>
<RBD image for temporary snap image>@<random snap name> <RBD image for k8s dst vol>
7)rbd snap rm <RBD image for src k8s volume>@<random snap name>

Next, apply the psp yaml. and stop the cluster and then restart it
