Some versions of minikube/docker add a "localhost/" prefix to imported
images. In that case, the image needs to get tagged without the prefix
as well.
When running podman2minikube.sh, the docker process inside the minikube
VM sometimes responds with:
# ./podman2minikube.sh rook/ceph:v1.3.9
Loaded image: localhost/rook/ceph:v1.3.9
When the "localhost/" prefix is added to the image name, deploying Rook
will try to pull the rook/ceph:v1.3.9 image again. This can fail when
the Docker Hub pull rate-limit is hit.
Without the "localhost/" prefix, there should be no further attempt to
pull the image, as it should be detected that the image is available.
