Can do action doesn't fail if there are no disks..
If there are no disks at this point then we need to finish the command
gracefully.

The "new" active snapshot is irrelevant in this case since we revert the images
to the old images, so the removed snapshot is actually what needs to go back to
being active, as it was the active snapshot before.

Currently this class has no test, so no need for premature optimization..

1. Currently this class has no test, so no need for premature optimization..
2. It is not a shared hierarchy.

It's done in the runAsyncTask method

Yes it's roll forward

This is unrelated change so i would rather not do it in this patch

Execute is not tested ATM so no need for premature optimization
