[stable-only]: Switch to uWSGI module

For some reason (pbr, setuptools, upper-constraints, devstack itself)
devstack can't find /opt/stack/data/venv/bin/magnum-api-wsgi

It's a partial cherry-pick of If8a155a3cebf8cd6a6d22ed7617f2777fbfac11f

buster-slim got moved to debian/eol
marking flannel jobs as non-voting for now
