Review comment:
What about removing this finally and boolean control variable? You only need
to worry about exception cases (normal workflow is already addressed at
567-568). So, you can do something like this in the catch block:
```
destroySnapshotOnPrimaryStorage(conn, snapshotUuid);
```
BTW: the method `destroySnapshotOnPrimaryStorage(Conn, String)` does seem to
need that boolean return and we also could remove its catch of `Exception`.
