Document that bulk update is available in Django 2.2

Hello @aykut! Thank you for this library and your work on it!

I just wanted to let you know that coming in Django 2.2 there will be a bulk_update() function available on any Model (just like bulk_create) that uses the same method as this library (and is heavily inspired by it!) 🎉 🎉

Would documenting this be possible? We could perhaps add a fallback to the built-in bulk_create if we are running in Django 2.2, to ease upgrading? We are also looking at adding support for specialized db-specific SQL to Django to speed this up, I’d love any input you may have!

Here are the docs for the new method

I’d like to really thank you for creating a reproduction repository @mikicz, it’s increadibly helpful and I wish everyones reproductions where as detailed as this!

I’ve created a ticket on the Django bugtracker (https://code.djangoproject.com/ticket/31202) and assigned it to myself. I’m somewhat busy right now but I promise that I will spend some time and see if I can dig more into this. I’ll update the ticket rather than this issue.

Thanks again for creating this test case.

@orf @Ehco1996 Django 2.2 is now released, and docs are no longer draft:
