RFR: Roles in the OpenJDK [v2]

[Jesper Wilhelmsson]

> Added a short intro about OpenJDK describing Groups, Projects, and different roles. The sections on how to progress through the Author, Committer, Reviewer roles needs a broad agreement since that's an area that affects everyone and where there historically has been a lot of debate. This is a first draft, please comment.
