Decommission several Persona.org domains

These domains still need to be decommissioned:
https://www.persona.org/
http://status.persona.org/
http://identity.mozilla.com/

Forgot to include: also decommission:
https://support.mozilla.org/en-US/kb/what-is-persona-and-how-does-it-work
https://developer.mozilla.org/en-US/Persona
It would probably also be a good idea to delete this group.
