[odrs-web/UBI8: 1/6] Switch Dockerfile to UBI 8 Python 3.8 image

[Bartłomiej Piotrowski <bpiotrowski src gnome org>]

commit 879d1a0d9ff42ae8a7ad1c39c06c712db73a1491
Author: Bartłomiej Piotrowski <bpiotrowski gnome org>
Date:   Fri Apr 22 12:46:18 2022 +0200

    Switch Dockerfile to UBI 8 Python 3.8 image
    
    Move various command to entrypoint script to avoid assumption of having
    direct database access during image build. Additionally, switch from
    mod_wsgi to gunicorn.
