[Python-modules-team] Bug#931592: python3-django: should suggest python3-mysqldb >= 1.3.13

[Zhang Jingqiang]

Package: python3-django
Version: 2:2.2.3-2
Severity: important

Dear Maintainer,

After upgrading to django 2.2.3-2, I get the following while starting
myapp:

django.core.exceptions.ImproperlyConfigured: mysqlclient 1.3.13 or newer is required; you have 1.3.10.

It will be good if we can conflict with python3-mysqldb < 1.3.13.
