If we stopped containerd, we restart dockerd.

If starting minikube a second time, do nothing.

When docker.service is *not* bound to containerd.service,
that means that it will be restarted to not try to use it.

Should avoid errors like: map has no entry for key "State"

When inspecting a volume, rather than a container or image

Fix gofmt, golint, and most of gocyclo
(but not the integration tests just yet)

And add a missing test for ImageExists function

To work on CentOS, which has a weird path in sudo

It has not been updated since kubernetes 1.9 or so

This only tests the happy path of the current iso versions.

It is only Docker that adds the "k8s_" prefix, since CRI
only handles containers that are used by Kubernetes anyway.

Also need to use "sudo" when running all crictl commands,
including logs. And only list containers that are running.
