1229: Fix docs warnings r=mergify[bot] a=muhlemmer

## What type of PR?

Documentation

## What does this PR do?

1. Fix various build warnings from Sphinx that sneaked into the project over time, and fixed them. 
2. Enable the `-W` option for `sphinx-build` to elevate `warning` to `error` in order to make build fail in case of syntax errors. This will give a better feedback from Travis to Pull Requests with Documentation updates. They will now block in case of syntax errors, so we don;t have to cleanup afterwards.
