#3000: Clients do not clear HS descriptor cache on SIGNAL NEWNYM

------------------------+---------------------------------------------------
Currently, Tor clients do not clear their hidden service descriptor cache
when they process a SIGNAL NEWNYM control port command. Thus, anyone who
can ‘tag’ a client with a unique HS descriptor, and then test for the
presence of that descriptor later, can track the client until the
descriptor expires up to 72 hours later or until it is stopped and
restarted, whichever happens first. We should fix this.
