Drop Django 1.11 support

Django 1.11 ends its extended support in April 2020 (which is before
Ussuri release), so horizon drops Django 1.11 support in Ussuri.

tox envs for non-primary Django versions are no longer needed in tox.ini
as testing environments for non-primary Django versions are setup in
the zuul jobs now.

horizon>=17.1.0 is required to use Django 2.2. requirements.txt and
lower-constraints.txt are updated accordingly. for more info. please
refer [1].
This patch also drop django-babel as horizon already swiched from
django-babel to enmerkar. congress-dashboard requirement.txt needs to
sync the change to fix gate failure. enmerkar, a successor of
django-babel will be installed via horizon, so we don't need to
have it in requirements.txt explicitly.

Depends-On: https://review.opendev.org/#/c/700733/
