+ Workarounds for aging python 3.5 on Ubuntu 16.04 builders
+ Ubuntu 16.04 calls a python2 version of tox we must upgrade
+ it even if we are testing with python3
+ ubuntu 16.04 runs python 3.5 we must pin the zipp package
+ more pins will be needed as packages drop support for python 3.5
+ ideally projects will move away from this distro.
