Description of problem:

Currently, the vTPM implementation requires an RWX storage class to be set. This makes using the feature problematic in some deployments. An example would be a Single Node OpenShift that lacks a RWX storage class.

Instead of blocking the ability for a VM to run, let's instead allow it, but impose the NotMigrateable status condition if a VM's vTPM or EFI are backed by an RWO storage class.

Hint: CDI maintains a database of storage class characteristics, so KubeVirt should be able to interrogate that for information. Care must be taken to ensure vTPM still works in clusters where CDI is not installed. KubeVirt should default to NotMigrateable, but allow the user an escape hatch to override.
