 This comes from #25882.

 Should a client claim that an IP is failing if the RP never connected? In
 other words, handling the `CIRCUIT_PURPOSE_C_REND_READY_INTRO_ACKED`
 purpose when cleaning up a circuit.

 I would think that having a maximum amount of retries let say
 (arbitrarily) after 2 times that you introduce, the IP sends back the ACK
 but then you end up timing out the RP circuit, we would flag the IP in the
 failure cache and move on to a new IP.

 This would not be a "catch all" issues with connectivity but would at
 least zone out buggy or malicious IP that do not relay the introduction.
