kind: adapt PVC vmi_configuration_test
kind: adapt PVC vmi_configuration_test

PVC volumes are mounted into libvirt w/ the `cache=none` parameter.
When kubevirt is deployed on  kind infrastructure, libvirt doesn't
accept that cache value, and instead logs a warning, and coerces
the value to `writethrough`.

This patch adapts the test when the kind infra is run.
