Add initial steps to dotty-bot

This PR will add a bot whose first purpose is to check the CLA of
contributing PRs. It improves on the old bot in that it checks each
commit individually, and doesn't get upset about 100+ commits.

It would be fun to do this PR with you @OlivierBlanvillain, feel free
to provide feedback/comments and refactor as you like
