主题：[openstack/requirements] Horizon image works abnormal because of the conflict bewteen mysqlclient and Django
Hello: 
    I have built a horizon image in ussuri version, but it works abnormal due to package mismatch problem.
    According to Django===2.2.12 from latest upper-constraint.txt, it is not compatible with mysqlclient.
    Using old version Django===2.1.5 can fix the problem.
    Could you help me to check the mismatch problem. 
    Many thanks.
