@jkaluza @lucarval PTAL. I think I covered everything, but I might have missed something...

I think, you can also remove funcsigs stuff (requirements.txt and freshmaker/events.py).

The python3-funcsigs is probably also not needed.

What in the world is python-fedora ?
UPDATE: Apparently it's "Python modules for talking to Fedora Infrastructure Services"
I don't think it's being used. Maybe we can remove it in a future PR. It's beyond the scope of this PR.

We should probably also remove the usage of six library and usage of from __future__.

It looks good for me. I think we can try merging that and see if it builds and works on freshmaker dev.

I've rebased addressing the comments.
I agree with Jan, once it's merged let's check if devs works correctly.

@lucarval @lholecek can you review again?
