--lint not loading sql_analyser option

[sondrelg]

Hi!

Thanks for creating and maintaining this. It looks useful 👍

I'm in the process of getting the linter set up for my project and have run into two small issues:

1. The django.contrib.gis.db.backends.postgis backend is not recognized. I think this could be mapped to postgresql safely, but I can't say for sure.
2. According to the docs you can specify the sql_analyser, but this isn't recognized when running the linter using makemigrations.

For the second issue, this is how config values are loaded and propagated when calling the linter management command. The same thing is unfortunately not done in the makemigrations management command here. The result is that I'm not able to run the linter using the --diff flag 🙂

Would you be open to fixing option 1 or 2 here? I'd really like to use MIGRATION_LINTER_OVERRIDE_MAKEMIGRATIONS 🙏

I probably have time to create a PR for either of these, but would love to know what you think before starting!
