Drop lower-constraints.txt and it's testing

As discussed in TC PTG[1] and TC resolution[2], dropping
the lower-constraints.txt file and its testing.
We will keep lower bounds in the requirements.txt file but
with a note that these are not tested lower bounds and we
try our best to keep them updated.

And switch to openstack-python3-zed-jobs
