The stripe-size is the most efficient size to write to RBD images.
However, not all images are a multiple of stripe-size large. That means
thick-provisioning would not allocate the full image, and the process
might even fail.
This adds a 50 MB PVC to test the process, 100 MB is coincidentally a
multiple of the (default 4 MB) stripe-size, 50 MB is not.

When deleting a PVC fails, the following messages are repeated until a
timeout is hit:
cephfs-80811 in state &PersistentVolumeClaimStatus{Phase:,AccessModes:[],Capacity:ResourceList{},Conditions:[]PersistentVolumeClaimCondition{},} to be deleted (600 seconds elapsed)
Because the Phase is not set, the PVC seems to be in a strange state. In
case this happens, log all details from the PVC so that we can identify
additional conditions to check for completed deletion.

When passing a pointer to a PVC and PV, the status of the deleted
objects is not logged correctly. The `PersistentVolumeClaim.Status` and
`PersistedVolume.Status` that is added to the logs contain the status of
the initially created object (reference to the PVC/PV). When the PVC/PV
is removed, there is no guarantee that the object is updated.
Logs show an empty (nullified) `PersistentVolumeClaim.Status`, which is
not helpful. Instead, use the returned PVC/PV from the `Get()` function
and use that for further logging. Even when the `.Status` struct from
the PVC/PV gets wiped, the returned object should have correct details.

The e2e tests create a Secret for using with the RBD StorageClass.
However this Secret was not used, instead the Rook generated Secret was
linked in the StorageClass.
By using our own Secret from the examples, Rook should not touch it when
we make modifications. In addition, no modifications are needed for
encryption anymore, as these are included in the example.

Once the Vault API removed a secret, the contents will have been wiped.
The key is still available, until it gets destroyed. This causes the e2e
test to detect an empty secret, and assume that it has not been deleted
yet.
By requesting the `data` field from the secret, an error is thrown in
case the secret has been wiped. This makes it possible for the e2e test
to detect that the secret has been removed and scheduled for destroying.

Go 1.13 contains support for error wrapping. To support wrapping,
fmt.Errorf now has a %w verb for creating wrapped errors, and three
new functions in the errors package ( errors.Unwrap, errors.Is and
errors.As) simplify unwrapping and inspecting wrapped errors.
With this change, If we currently compare errors using ==, we have to
use errors.Is instead. Example:
if err == io.ErrUnexpectedEOF
becomes
if errors.Is(err, io.ErrUnexpectedEOF)
