#16558: DIr auths should vote about Invalid like they do about BadExit

------------------------------+------------------------------------
 Right now only three dir auths put BadExit in their known-flags, so it
 takes any 2 of those 3 to give a relay the BadExit flag, which causes an
 exit relay to not be used by clients for exiting. This is a great
 convenience for the dir auth operators, since otherwise we'd have to get a
 majority of all nine (i.e. five) dir auth operators to declare that a
 relay shouldn't be used for exiting, and we'd be much less agile in
 response to detected bad behavior.

 In comparison, all nine relays put Valid in their known-flags, so it takes
 a full 5 of the 9 to give a relay the Valid flag -- or said another way,
 it takes a full 5 of the 9 to take it away.

 In the context of malicious HSDir roles, this lack of agility is hurting
 us. We should explore ways to make !invalid more like !badexit.
