Python 3 progress

[Tomas Kopecek]

Based on yesterday's discussion in community meeting, I've gone through all
my work on python3 and rebased all branches. So, if you're willing to test
it, here they go:

1) web - most simple and safe: https://pagure.io/koji/pull-request/891
2) hub - https://pagure.io/koji/pull-request/921
3) builder - https://pagure.io/koji/pull-request/1117 (mostly WIP, without
packaging changes, ...)
