automation: create Python 3.5 variant of requirements.txt

The automation environment is refusing to build with the previous
file because some dependencies won't install on Python 3.5.

I couldn't find an easy way to salvage the situation with a single
requirements.txt file. So, I decided to introduce a variant
for Python 3.5.

As part of this, we update packages to latest versions.

(I do question why we are still supporting Python 3.5...)
