Workflow iterator continues on faillure (#18325)

New status `FAIL_SAFE` added. This status propagates to the following
nodes until reaching the iterator, that will start the new iteration.

The difference with `SKIP` is that, when the parent nodes have at least
one `FAIL_SAFE`, it becomes `FAIL_SAFE` too. While a parent 1 `SKIP` +
parent 2 `SUCCESS` => to be executed.

I also thought about just going back to the iterator as a break would,
but since we have branches, it may lead to inconsistent statuses with
parallel updates.
