 Currently Tor can expose a circuitid to backends with directive
 HiddenServiceExportCircuitID using the HAProxy proxy protocol, but because
 there could be multiple Tor instances accessing the same backend (e.g.
 onionbalance) circuitids could collide.

 I propose a config directive HiddenServiceExposeInstanceID, which enables
 users to specify a tor instance ID which can be placed instead of
 dead:beef:4dad.

 If this seems ok, I’ll whip up a simple patch.
