[P2P] Trusted contacts for peer-to-peer calls

Just to add to this: Hampus mentioned in Fluxer labs that there will be a visible warning before joining a P2P call. https://web.fluxer.app/channels/1519773906704011264/1541839434838716417/1558924663784996864

it will tell you that your IP address will be visible to the others in the call before you initiate it that way

So I think the way this feature request would manifest would be more like "Calls with these trusted contacts will not bring up this alert". One might argue Friends should suffice for this list, but people tend to use their Friends list for different things so perhaps this is for an even closer social circle.
