List project contacts and escalation in CoC
@danvet and @seanpaul pointed out that the CoC is not always particularly clear on how to proceed for people.
Specifically, we should list the points of contact for projects (and periodically check these are still current/appropriate), as well as explicitly call out that we expect project contacts to be the default point of call, with us either as escalation or if the person reporting doesn't feel comfortable with the project maintainers.
When we're collating the list of all our projects (#2 (closed)) together, we should obtain these contacts with them, as well as have a discussion about the CoC in general.
