There are a lot of python utilities that in a perfect world would live in their own virtualenv and not mess with the system python.
A project called pipsi does this locally:

I have fiddled around with trying to accomplish the same thing using ansible. Never developed an ansible module before - there is a lot missing and it is very rough but it solved my very simple needs.

My solution is a bit hacky in comparison to the pipsi code and I imagine it misses various edge cases. I read over the pipsi code but I am not sure why it does what it does with the console scripts - for that I would need to understand python packaging more. Programming is a never ending loop of trying to eradicate my own ignorance. So it may be harder to implement something worthy of ansible core than I have time to devote to the problem.
