Description

We should add a new option for the hotstart, to better handle failed evaluations.

Current behavior

During hotstart, if any evaluations failed, the same fail flag will be passed to the optimizer, creating a consistent hotstart "replay".

Expected behavior

Add a new option, so that at the first instance of a failed evaluation, an actual evaluation is done. This would be useful if the user has adjusted some solver settings, in order to prevent the original failure. This would of course break the hotstart and any evaluations after that would be actual evaluations not from the history file. So ideally, this would be useful if the only failure happened near the end of the optimization. Eventually, we may want to provide more granular controls over exactly which fail flag we want to re-evaluate during the hotstart, via callCounter indexing.
