Snapshot cloning

As a user I would like to be able to clone from VM level snapshots using “hypercore” collection.

Some minor changes are suggested.

A major change is requirement to clone VM from automated snapshot. This makes things complicated, since automated snapshot have duplicated labels. We can simulate this case by creating two USER snapshots with duplicated label.

Nonunique labels were reason we used source_snapshot_uuid as snapshot identificator in #179 (sorry, not in main yet). Discussion about how to identify snapshot was long, and there are other alternatives (snapshot serial, label, date as "latest snapshot created before date X" etc). But all those alternatives are more complicated to implement.

By using source_snapshot_uuid as parameter name we can implement something nicer later, in backward compatible way. I believe vm_snapshot_info can be used to list snapshosts with specific label, then user can assert in playbook a single snapshot was returned, or can decide which of N snapshots to use.

I think there is trivial typo in integration test. Atherwise, all good. Ty.

Added duplicate snapshot label cloning to integration tests.
Fixed typos in vm_clone.

Fixed typos.
