Freeze requirements data per python version

Rather than using the same (default) python for all of the
requirements files in `requirements/*.in`, specify it more strictly
by making each supported python version map out to a set of
requirements files.

The mapping is that for any `requirements/foo.in`, we produce
`requirements/py{major}.{minor}/foo.txt` for all python versions we
support. `major.minor` aligns with the `{py_dot_ver}` available under
`tox`, making it trivially easy to then refer to these built
requirements from `tox.ini`.

There is one tweak to pin back the version of `pip` under py3.7 in
order to support an older pip-tools version.
