When running on AWE EC2 virtual-machines, we'll use Podman instead of
installing a VM. The "none" driver might work as well, but it requires
additional dependencies to be installed, which may change over time with
new minikube or Kubernetes releases. Hopefully the Podman driver is less
affected with changes in dependencies.

The scale down/up functions fail often with "deployment not found"
errors. Possibly deploying with Podman is slower than deploying in a
minikube VM, and there is a delay for the deployment to become
available.

In case `wget` is not installed, downloading the Helm release will fail.
The `install-helm.sh` script won't return a fatal error in that case,
and CI jobs continue running in an environment that is not ready.

By adding a check that exist the script with a failure, the CI will now
correctly report a problem when Helm can not be downloaded.

There are occasions where deleting a PVC (or PV) never succeeds. The
reported status of the deleted object is sometimes empty, which suggests
that the PVC or PV was, in fact, deleted.

To diagnose the incorrect error checking, include the errors for
retrying in the logs.

Because the rbd-nbd tests fail with minikube and the Podman driver,
disable the tests for the time being.

CephFS does not have a concept of "free inodes", inodes get allocated
on-demand in the filesystem.

This confuses alerting managers that expect a (high) number of free
inodes, and warnings get produced if the number of free inodes is not
high enough. This causes alerts to always get reported for CephFS.

To prevent the false-positive alerts from happening, the
NodeGetVolumeStats procedure for CephFS (and CephNFS) will not contain
inodes in the reply anymore.
