Migrate from previous versions

Releases on PyPi before 3.0.0 are published from repository https://github.com/blacktear23/django_tidb. This repository is a new implementation and released under versions from 3.0.0. No backwards compatibility is ensured. The most significant points are:

• Only Django 3.2 and 4.0 are tested and supported.
• Engine name is django_tidb instead of django_tidb.tidb.

Known issues

• TiDB does not support FOREIGN KEY constraints(#18209).
• TiDB does not support SAVEPOINT(#6840).
