Write onboarding/offboarding guidelines/checklists for various roles

We currently have no onboarding or offboarding guidelines nor checklists for our roles. This is bad. Write guidelines for these roles:

• DevOps
• TU
• Dev
• Security Team
• Bug Wrangler
• Forum Admin
• Wiki Admin
• IRC Operators/Mods

Ask people who are currently involved in those roles to contribute some roles.

Previous work:

• Developer Checklist
• TODO list for a new TU
• TODO retiring a TU

We need onboarding automation as this is currently painful:

• Does mailman allow automation of onboarding/adding users (staff list for example)
