The previous function used to remove omap keys apparently did not
return errors when removing omap keys from a missing omap (oid).
Mimic that behavior when using the api.

For any function that sets more than one key on a single oid setting
them as a batch will be more efficient.

Taking this appraoch means that any function that must get more than one
key's value from the same oid can be more efficient by calling out to
ceph only once.
To be cautious and avoid missing things we always request ceph return
more keys than we actually expect to be set on the oid. If there are
unexpected keys there, we will not miss the keys we want if we first hit
an unexpected key if we were to limit ourselves to iterating only over
the number of keys we're expecting to be on the object.

Convert the business-logic of the journal to use the new go-ceph based
omap manipulation functions.

These new omap manipulation functions (get/set/remove) are roughly
equivalent to the previous command-line based approach but rely

go-ceph v0.3 adds constants for ImageFeature values and their names.
Instead of hardcoding "layering" in several places, use the constant
given by librbd.
The rbdVolume.ImageFeatures does not seem to be used anywhere after the
conversion. Stashing the image metadata does include the ImageFeatures
as these are retrieved when getting the image information. It is safe to
drop ImageFeatures altogether and only use the imageFeatureSet instead.

It seems that convering the release component from the unix.Utsrelease
type leaves some trailing "\x00" characters.
While splitting the string to compare kernel versions, these additional
characters might prevent converting the string to an int. Strip the
additional characters before returning the string.
Note:
"\x00" characters are not visible when printing to a file or screen.
They can be seen in hex-editors, or sending the output through 'xxd'.

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)

This prevents the need to open the IOContext for additional operations
on the image.
It also addresses a leak of the IOContext in case `rbdVolume.open()` was
called. The method only returned the `rbd.Image` without the possibility
to close the related IOContext.

In some Linux distributions the /etc/resolv.conf file is a symlink. This
file gets included in the Kubernetes containers and will be used for
resolving hostnames. By including the symlink, it is possible that that
target file is not available in the container(s). This will cause
problems when resolving hostnames, and Kubernetes will not get deployed.
The default minikube VM provides /run/systemd/resolve/resolv.conf, with
/etc/resolv.conf being a symlink. Therefor, it is needed to pass the
`--extra-config=kubelet.resolv-conf=..` parameter to `kubeadm`.
In case minikube is started with `--vm-driver=none` and
/run/systemd/resolve/resolv.conf does not exist, the local
/etc/resolv.conf will be used for inclusion in the Kubelet container. If
this is a symlink, the final destination should get passed with
`--extra-config=kubelet.resolv-conf=..` so that a working hostname
resolution configuration is available in the container.

Added a test case to cover unmap of rbd image

happens it should not block the rbd pvc deletion
