Release Note Label

Hi gang,

We’re going to try an experiment to help with release note production. If you submit a PR or if you review a PR which contains some changes worthy of being mentioned to customers, slap the flag/need-release-note label on the PR.

This label will serve as a reminder that when we put together release notes, we should consider adding a bullet item or two to describe what this PR is doing.

Please let me know if you have any questions.
