Add workload test: KubeVirt/Containerized-Data-Importer

# Describe the feature you'd like to have #

[Containerized-Data-Importer](https://github.com/kubevirt/containerized-data-importer) is a [KubeVirt](https://kubevirt.io) project that can work with CSI drivers. It is a straight forward workload that exercises many features of Ceph-CSI. In case a change breaks an external consumer like CDI, developers working on Ceph-CSI need to have a look at the cause and address it.

# What is the value to the end user? (why is it a priority?) #

Less chance on regressions for common consumers.

# How will we know we have a good solution? (acceptance criteria) #

There should be a CI job that runs the CDI smoke/happy-path tests regularly, possibly for each PR.

# Additional context #

See-also: kubevirt/containerized-data-importer#1289

Start by reading the CDI smoke/happy-path tests and the linked Containerized-Data-Importer issue #1289. Then trace how Ceph-CSI CI jobs are configured and determine how to run those tests regularly, with success defined as a CI job covering the CDI workload without regressions.
