Before deleting old attachment pod, wait for new attachment
pod to be ready, so k8s should not detach the volume from the
node since there will always be a pod using the volume from
its perspective.

Fixed issue where when adding or removing a volume the existing
volumes would still have the UID of the old attachment pod in
the VMI status which caused errors to appear in the virt-handler
logs about not being able to find the device or image.

Fixed issue where the cleanup would attempt to remove a volume
that was already gone causing errors to appear in the virt-handler
log.
