hsv3: Client do not report failing circuit back into HS subsystem
This is a subtask of the bigger larger problem in #25882 (moved).
A v2 client does report intro point failures within
circuit_about_to_free() but not v3.
Actually, any HS circuit client side is not looked at. The
hs_circ_cleanup() was intended for this as the entry point in the HS subsystem but only the service uses it.
Intro circuit failure needs to be noted in the failure cache (
Rendezvous circuit need to be also somehow handled. If the RP circuit keeps closing on us, we might want to stop trying maybe?
Same goes for HSDir circuit, if they close, client needs to be notified and launch a refetch.
