Comment (by asn):
One approach here is to indeed define new circuit purposes for HS
circuits. My main fear here is that these circuit purposes are used for
tons of things in the codebase (from circuit timeouts, to cannibalization,
to guard stuff, to stats stuff, to basic circuit functionality state
machine), and hence adding new purposes means that we need to find
'''all''' the right places to consider our new purposes which I imagine is
gonna be a PITA and perhaps error-prone...
Another approach would be to use the `hs_ident` and `rend_data` elements
of the `circuit_t` to distinguish HS circuits from normal circuits. That's
what most of the code is doing to detect HS rend circuits.
