This repo has not been testing lower-constraints at all due to
broken install_command. If you look at any lower-constraints run and
compare the install python packages with lower-constraints, you see
that those are completely different.
This change removes install_command and updates deps in tox.ini to
follow best practices (moving constraints into deps).
It also updates lower-constraints to newer versions.
Remove broken hacking test.
