List CODEOWNERS, role, and responsibilities

james-dow created the following on Apr 26:

As a collaborator I need to know who I can request to review my pull request so my work doesn't get lost in the noise

Adding a CODEOWNERS file to our repositories can do two things for us. One it'll give a clear place where our contributors can see who is responsible for what. Second it automatically assigns the correct person when that section of the repository is touched, so they are made aware and can review.
