scripts: Add a gen_release_notes.py script

This script is responsible for generating an entire page in the
docs/relnotes/ directory. It includes a template for the page, and uses
mako to fill in the necessary bits. It is designed to be purely fire and
forget, calculating previous versions, shortlogs, bug fixes, and dates.
