Issue:
db support for CockroachDB
I would like to propose a feature that django-eviron's `db()` parser shall support CockroachDB

[CockroachDB](https://www.cockroachlabs.com/) is a distributed quorum based database. Cockroach Labs have provided an [idiomatic driver for Django](https://github.com/cockroachdb/django-cockroachdb).

This driver does under the hood use psycopg, so in theory a postresql:// connection string could be used with `Env().db_url()` (I have not tried!) it is preferable to use the Cockroach driver as this improves resiliency and retry logic.

I am all too happy to submit the PR for this myself.

Discussion:
@stevewilliamsuk: Would also add that it is worth considering support for djongo as well: https://www.mongodb.com/compatibility/mongodb-and-django#connect-django-and-mongodb-using-djongo@sergeyklay: Implemented in https://github.com/joke2k/django-environ/pull/511 so I close this one. Thank you contributing!
