Add tags to pull request based on codeowners

[maxking]

Today, Python uses "codeowners" features to notify the team that owns the part of the code where there is a new PR, but there seems to be no way for non-core developers (or, more generally, people who are not in the "team") to filter pull requests by component.

My personal need to have a filter for emails to review for python/email team, but I am not a part of it. I am not sure if there is enough data for this bot to do that, but if the PR metadata has this codeowners information, we could use a team->tag map of some sort.

Would this be something you'd be willing to add? If yes, I could possible contribute code/help someone else to do that.

Also, I do want to mention that I looked at the advanced search syntax for PRs and it doesn't allow searching by "codeowners". It does allow searching by @mention.

So, my goal would also be satisfied if this bot could @mention the team. Although, core team members might not want emails/notifications on every new PR and might affect their personal workflows.

Thanks for the suggestion, I think it is great idea, and something I'm thinking for PEP-588.

It is however out of the scope of the-knights-who-say-ni (for CLA enforcement).
Can you re-open this issue in either core-workflow or bedevere? I think the codebase change will likely be in bedevere.

@Mariatta Done! Closing this one.
