Somehow deleteDatastore was never implemented, that meant:
templates haven't been cleaned up on datastore delete and
also agents have never been informed about storage pool removal.
DeploymentPlanner.addPod takes long value while
VmInstanceVO.getPodIdToDeployIn returns a Long value which can be null
when the VM is never started.

If a -rst resource wasn't deleted because of a failed copy,
a reoccurring snapshot attempt couldn't be done, because there
was still the "old" -rst resource. To prevent this always
try to remove the -rst resource before, if it doesn't exist it is a noop.
