RFC: Document Clippy's teams and team duties

First the big announcement:

**We want to add a new subteam for regular contributors to give them triage rights.**

---

This PR adds a new section to the book which describes the Clippy and Clippy-Contributor teams, with their duties and membership requirements. This is just an initial draft, that outlines what, I think, their responsibilities should be.

I hope everyone in the team is okay with me posting this directly to GitHub. I think a PR makes collaboration a bit easier.

---

Once we've decided on this document, I'll create a PR to add the new team on GitHub. As part of this, we'll also reach out to some active contributors, to ask if they would like to join the new team.

+# The team
+
+Everyone who contributes to Clippy makes the project what it is. Collaboration
+and discussions are the lifeblood of every open-source project. Clippy has a
+very flat hierarchy. The teams mainly have additional access rights to the repo.
+
+This document outlines the onboarding process, as well as duties, and access
+rights for members of a group.
+
+All regular events mentioned in this chapter are tracked in the [calendar repository].
+The calendar file is also available for download: [clippy.ics]
+
+## Everyone
+
+Everyone, including you, is welcome to join discussions and contribute in other
+ways, like PRs.
+
+You also have some triage rights, using `@rustbot` to add labels and claim
+issues. See [labeling with @rustbot].
+
+A rule for everyone should be to keep a healthy work-life balance. Take a break
+when you need one.
+
+## Clippy-Contributors
+
+This is a group of regular contributors to Clippy to help with triaging.
+
+### Duties
+
+This team exists to make contributing easier for regular members. It doesn't
+carry any duties that need to be done. However, we want to encourage members of
+this group to help with triaging, which can include:
+
+1. **Labeling issues**
+
+    For the `good-first-issue` label, it can still be good to use `@rustbot` to
+    subscribe to the issue and help interested parties, if they post questions
+    in the comments. 
+
+2. **Closing duplicate or resolved issues**
+
+    When you manually close an issue, it's often a good idea, to add a short
+    comment explaining the reason.
+
+3. **Ping people after two weeks of inactivity**
+
+    We try to keep issue assignments and PRs fairly up-to-date. After two weeks,
+    it can be good to send a friendly ping to the delaying party.
+
+    You might close a PR with the `I-inactive-closed` label if the author is
+    busy or wants to abandon it. If the reviewer is busy, the PR can be
+    reassigned to someone else.
+
+    Checkout: https://triage.rust-lang.org/triage/rust-lang/rust-clippy to
+    monitor PRs.
+
+While not part of their duties, contributors are encouraged to review PRs
+and help on Zulip. The team always appreciates help!
+
+### Membership
+
+If you have been contributing to Clippy for some time, we'll probably ask you if
+you want to join this team. Members of this team are also welcome to suggest
+people who they think would make a great addition to this group.
+
+For this group, there is no direct onboarding process. You're welcome to just
+continue what you've been doing. If you like, you can ask for someone to mentor
+you, either in the Clippy stream on Zulip or privately via a PM.
+
+If you have been inactive in Clippy for over three months, we'll probably move
+you to the alumni group. You're always welcome to come back.
+
+## The Clippy Team
+
+[The Clippy team](https://www.rust-lang.org/governance/teams/dev-tools#Clippy%20team)
+is responsible for maintaining Clippy.
+
+### Duties
+
+1. **Respond to PRs in a timely manner**
+
+    It's totally fine, if you don't have the time for reviews right now.
+    You can reassign the PR to a random member by commenting `r? clippy`.
+
+2. **Take a break when you need one**
+
+    You are valuable! Clippy wouldn't be what it is without you. So take a break
+    early and recharge some energy when you need to.
+
+3. **Be responsive on Zulip**
+
+    This means in a reasonable time frame, so responding within one or two days
+    is totally fine.
+
+    It's also good, if you answer threads on Zulip and take part in our Clippy
+    meetings, every two weeks. The meeting dates are tracked in the [calendar repository].
+    
+
+4. **Sync Clippy with the rust-lang/rust repo**
+
+    This is done every two weeks, usually by @flip1995.
+
+5. **Update the changelog**
+
+    This needs to be done for every release, every six weeks. This is usually
+    done by @xFrednet.
+
+### Membership
+
+If you have been active for some time, we'll probably reach out and ask
+if you want to help with reviews and eventually join the Clippy team.
+
+During the onboarding process, you'll be assigned pull requests to review.
+You'll also have an active team member as a mentor who'll stay in contact via
+Zulip DMs to provide advice and feedback. If you have questions, you're always
+welcome to ask, that is the best way to learn. Once you're done with the review,
+you can ping your mentor for a full review and to r+ the PR in both of your names.
+
+When your mentor is confident that you can handle reviews on your own, they'll
+start an informal vote among the active team members to officially add you to
+the team. This vote is usually accepted unanimously. Then you'll be added to
+the team once you've confirmed that you're still interested in joining. The
+onboarding phase typically takes a couple of weeks to a few months.
+
+If you have been inactive in Clippy for over three months, we'll probably move
+you to the alumni group. You're always welcome to come back.
