FEATURE REQUEST: If pre_upgrade fails, revert canister to earlier state snapshot of before pre_upgrade ran and discard current pre_upgrade logic

I suppose the trade off here is that it could be an expensive operation. There was a feature mentioned at some point that would allow backing up and restoring canisters. Not only might that mitigate some of the risk around upgrades, it could potentially be used to test upgrades locally with a similar volume of data as in a production environment.
