replace volume_support_qemu_snapshot with volume_qemu_snapshot

This also changes the return values, since their meanings are rather
weird from the storage point of view. For instance, "internal" meant
it is *not* the storage which does the snapshot, while "external"
meant a mixture of storage and qemu-server side actions. `undef` meant
the storage does it all...
