Adds five new test cases to test_backup_recovery_nas.py covering the
end-to-end behaviour of the incremental NAS backup feature:
* test_incremental_chain_cadence
- Sets nas.backup.full.every=3, takes 5 backups, verifies the
type pattern is FULL, INC, INC, FULL, INC.
* test_restore_from_incremental
- FULL + 2 INCs, each with a marker file. Restores from the
latest INC and verifies all three markers are present
(i.e. qemu-img convert flattened the chain correctly).
* test_delete_middle_incremental_repairs_chain
- Builds FULL, INC1, INC2; deletes INC1 (no force needed);
restores from the surviving INC2 and verifies that markers
from FULL, INC1 (which was deleted), and INC2 are all present
— proving the rebase merged INC1's blocks into INC2.
* test_refuse_delete_full_with_children
- Verifies plain delete of a FULL that has children fails, and
delete with forced=true succeeds and removes the whole chain.
* test_stopped_vm_falls_back_to_full
- Sets cadence to 2, takes one backup (FULL), stops the VM,
triggers another (cadence would say INC). Verifies the second
backup is recorded as FULL because the agent fell back when
backup-begin couldn't run on a stopped VM.
All tests restore nas.backup.full.every to 10 in finally blocks.
