doc: Improve contribution guidelines
- Add some guidance about the type of information a patch author should
provide to facilitate the review (and for future reference).
- Make a number of implicit expectations explicit:
- Every patch must compile.
- All CI tests must pass.
- Mention that the patch author is expected to add reviewers and explain
how to choose them.
- Explain the patch submission rules in terms of Gerrit labels.
Also do some cosmetic changes, like adding empty lines, shuffling some
paragraphs around.
