sap_vm_provision/kubevirt_vm: Make evictionStrategy configurable

Move evictionStrategy from spec.template.spec.domain (wrong API level,
silently ignored by KubeVirt) to spec.template.spec (correct level).
Expose as variable sap_vm_provision_kubevirt_vm_eviction_strategy,
defaulting to None for compatibility with ReadWriteOnce storage.
Users can override to LiveMigrate when using shared storage (RWX).
