Modelled on TEST-87-AUX-UTILS-VM.bind-volume.sh. Boots vmspawn with
one boot-time bind-volume, hot-adds a runtime volume via machinectl
bind-volume, then exercises ReplaceStorage:
1. happy-path replace of a runtime drive
2. successive replace (verify file_generation rotation — no
node-name collisions on the second swap)
3. replace of the boot-time drive must fail with StorageImmutable
4. replace of an unknown name must fail with NoSuchStorage
5. invalid name (no provider:volume separator) must fail with
InvalidParameter
6. unbind-volume after replace must succeed — proves the new file
node is monitor-owned and the format-then-file teardown order
in vmspawn_qmp_block_device_teardown() correctly cleans up both
blockdev nodes
Pushes the new backing file via varlinkctl --push-fd; the file is a
plain truncate'd image. Auto-discovered by run_subtests in
TEST-87-AUX-UTILS-VM.sh.
