[tor-commits] [tor/master] hs: Improve logging

    hs: Improve logging
    
    Also demote a log message that can occur under natural causes
    (if the circuit subsystem is missing descriptors/consensus etc.).
    The HS subsystem will naturally retry to connect to intro points,
    so no need to make that log user-facing.
