in-repo changelogs

Some people like to keep release notes in the repo.

To do so generally means a release note update commit for every commit on trunk (aka. 50% git history noise) since dripip is designed for making a canary release for every trunk commit.

Dripip should make that possible though for those that want this tradeoff. They have the following options to be specific:

• accept 50% git history noise
• don't make canary releases
• don't update the release notes on canary releases

I can't think of any other ways to trade things off.
