Github OAuth Authorization API deprecation

[mluypaert]

The release process for azanium currently depends on python package github3.py (version 1.0.0a4) and the github3.authorize function to authenticate to Github using password authentication. This form of authentication is officially deprecated by Github (see here and here) and will be removed from the Github APIs on November 13, 2020. Hence there is a need to update this step in the release flow, as it would fail from November 13 onwards.

I've implemented a potential fix in 02bf1db, but am unsure whether this will cover the upcoming Github API deprecation (or what parts of Github3.py will be affected by it). As I don't know of a way to test this upfront (I've missed the brown-out periods), I will wait with creating a new db-migration (azanium) release until after November 13, at which point the Github OAuth Authorization API is being deprecated and the release process will fail if my code update would not cover the required changes.

The current release process is broken and it seems like this might be related to this ticket, reopening.
