------------------------------+--------------------------------
 In the periodic heartbeat messages, if I have one or more onion services
 configured, I want to hear (a) how many INTRODUCE2 cells I received since
 the last heartbeat, and (b) how many times circuit_launch_by_extend_info()
 got called with purpose CIRCUIT_PURPOSE_S_CONNECT_REND since the last
 heartbeat. These stats would have helped to discover #24894 and #24895.

 There's probably a good argument for also hearing "(c) how many times we
 successfully established a joined rendezvous circuit", but that turns out
 to actually be a bit hard to track, since it looks like there's no
 explicit "it worked" acknowledgement in our protocol (whoops). We could
 approximate it with "number of times we sent a RENDEZVOUS1 cell, and the
 next cell we got in response was not an END cell with reason
 END_CIRC_REASON_TORPROTOCOL"?
