Specify "tunnelled-dir-server" in dir-spec.txt
Looks like relays started advertising "tunnelled-dir-server" in their descriptors:
https://gitweb.torproject.org/tor.git/commit/?id=1ceb7142a131bd8706663d2b3c27d66a2dcb2a46
But there's no mention of that in dir-spec.txt.
It's just "tunnelled-dir-server"
without any arguments, right?
