Description

Following #31468 and a ​discussion on django-developers with broad consensus, change the way migrations are automatically named from date-based to operation-based. That is never name migrations based upon the current date (auto_YYYYMMDD) and instead always based on the operations they contain, rather than the current behaviour which uses either style.

It looks like a luke-warmish OK on the list, so I guess we should push it forward to review. Thanks Adam.

Just a vague idea but I personally feel would be good to implement. In order to avoid ellipsis in the name refer ​this comment. We may add a suffix like "_+26" (in case there are 26 other operations, we may get this number from fragments ).
This is just a vague representation but I feel if we may implement something like this, it would be a better option. Need some suggestions.
I would be happy to submit a PR for this.
