Experiment: Auto-generated configuration reference

[sh-rp]

Description

This PR is an experiment to generate a docs page from our config specs to see wether this is viable / useful. This is still very hacky code and will be cleaned up a bit into a proper tool if we want to do this. We use ast to get the docstrings and the already existing configspec mechanism to collect all configspecs.

Notes:

• Right now the script only renders destination and credentials configurations in their own groups, the rest gets dumped at the bottom, also there are some Baseclasses we probably do not want to render in the final version
• This script should also enforce a docstring for every config class as well as a docstring for every property. If there is a docstring on a property of the same name in any class in the inheritance hierarchy, this one will be taken and it should pass (this is implemented already)
• This page should be checked into the repo and not generated on the fly, much like the cli docs. We also need a script for ci to verify that it is up to date.
