Add warning to 1.8.x users about Early Stopping and min_epochs interaction

[thesofakillers]

Description & Motivation

I wasted a lot of GPU compute and time trying to figure out why I was getting issues similar to #15708, #17813, and #18063. I thought something had been corrupted in my checkpoint due to the SLURM cluster I work on being iffy, but it turns out it was something as simple as an early-stopping and min_epochs conflict not being handled. I didn't think that something as simple as this would be the source of my issue.

Pitch

I see that the fix (#16719) has only been deployed to >1.9 users in the 1.9.2 release.

It would be nice to at least have a warning to users in 1.8 that using min_epochs with early stopping causes unwanted behaviour, to prevent users from wasting time and resources.

Alternatives

Merging the fix into 1.8 as well would be nicer of course.

Hello @thesofakillers
Thanks for the suggestion. Unfortunately, we don't maintain 1.8.x anymore. We do it for 1.9.x and 2.0.x, but we don't have the capacity to maintain ones older than that. Of course, there is nothing wrong with your proposal and if we had the capacity, we would do it. Thanks for helping out with commenting on the related issue pages.
