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.

The 'testpackage' linter recommends "black box" testing, which prevents
testing internal/non-exported functions from being tested. We have tests
that *do* test non-exported functions and types.
Disabling the linter allows us to test non-exported types and functions.

Rook version is currently 1.1.7 in our e2e deployment which brings 14.2.4 version
of ceph cluster. To support cephfs snapshot e2e, we need latest version of Ceph Cluster
in E2E. Rook 1.2.7 is good enough which on patching bring up ceph 14.2.10 cluster.

In some ceph version if the subvolume is not present, the
ceph returns doesnot exists and in some version not found
error message. This commit fixes issue for both error
checks.
By only checking Error ENOENT: for doesnot exist seems good.
even if some error message changes in ceph ceph-csi wont get
any issue.
```bash
sh-4.2# ceph version
ceph version 14.2.10 (b340acf629a010a74d90da5782a2c5fe0b54ac20) nautilus (stable)
sh-4.2# ceph fs subvolume getpath myfs csi-vol-a24a3d97-c7f4-11ea-8cfc-0242ac110012 --group_name csi
Error ENOENT: subvolume 'csi-vol-a24a3d97-c7f4-11ea-8cfc-0242ac110012' does not exist
```
```bash

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>

With minikube versions greater than 1.6.2 and less than 1.11.1, the YAML files
minikube path will not be automatically applied to the cluster. we will get
errors during bootstrap of the cluster if the admission controller is enabled.
To use Pod Security Policies with these versions of minikube, first start a
cluster without the `PodSecurityPolicy` admission controller enabled.
Next, apply the psp yaml. and stop the cluster and then restart it
with the admission controller enabled.
```
minikube start
kubectl apply -f /path/to/psp.yaml
minikube stop
minikube start --extra-config=apiserver.enable-admission-plugins=PodSecurityPolicy

As the maximum time allocated for the Travis
CI is 50 minutes and the cephfs and rbd E2E
