 The bootstrap tracker work in #27167 adds distinctions (in the form of
 additional bootstrap phases) between connecting directly to a relay vs
 connecting through a proxy.  It also tries to distinguish proxies from
 PTs.

 The changes to do the distinguishing between PT vs proxy don't work,
 because `conn->proxy_type` gets set to the protocol type of the underlying
 protocol that tor uses to talk to the PT locally.
