 Sebastian reported on #tor-dev that directory authorities can't set
 MyFamily, because it makes the relays in the family get marked as not
 Running.

 I'm not sure if this restriction is in the connecting code on authorities
 or relays, or the accepting code on relays.

 If it's on the connecting side, we can disable it on authorities.

 If it is in the accepting code on relays, maybe we need to keep it as a
 defence in depth measure. But we could disable it for authority IP
 addresses. (It wouldn't work with multiple authority IPs or
 OutboundBindAddress, but that's getting obscure.)
