Python3 support

This branch is based on GitLab-CI support, and should be merged after !1 (merged).

We added support for both python2 and python3 in the codebase, but it still has python2 hard-coded. For now we are patching the interpreter used in omnibus to change it to python3 to keep backward compatibility with users using it by source. In the near future, we will make this switchable with the help of an initializer.

I think this is acceptable. We are keeping the previous default behaviour for python 2.x and patching for python 3. We had this in omnibus-gitlab as a patch but by bringing it here every type of installation benefits.

@rspeicher Assigning to you for review as second pair of eyes.
