Collision in requirements

[DavHau]

The the requirements specified by the wheel distribution of renku 0.11.1 result in a python environment with colliding packages gitdb and gitdb2. See here: DavHau/mach-nix#101

The python package manager of your choice might ignore this collision, but that doesn't solve the issue itself
There are two different libraries with the same import path.
Therefore one doesn't really know which package is being used during runtime.

The problematic part of the dependency tree is:

renku - 0.11.1 - wheel
│
├── gitdb2 - 3.0.1 - wheel
├── gitpython - 3.1.0 - wheel
│   └── gitdb - 4.0.5 - wheel
│       └── smmap - 3.0.4 - wheel

The problem can either be fixed by removing the requirement gitdb2 or my patching gitpython upstream to also require gitdb2 instead of gitdb

Thanks for opening the issue @DavHau! I am transferring it to the renku-python repo, where it can receive the proper attention.

Nice catch! gitdb2 is a direct mirror of gitdb, since the devs had lost access to the gitdb package for a while ( gitpython-developers/gitdb#59 ). Since they have access again since ~2017, we should switch back to gitdb in the renku-python requirements.
