da40d8e05e rbd: use librbd.FeatureSet for features
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.

ebe378c79a util: trim "\x00" characters from the kernel version
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'.

323cc0e3bb cleanup: avoid comparing errors directly
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)

81b17c5157 ci: pass target filename of /etc/resolv.conf in case it is a symlink
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.
