Increase the conflict acceptance test launch delay

[teor2345]

Motivation

The Windows CI failed the metrics_conflict test, because node1 opened its listener after node2:
https://github.com/ZcashFoundation/zebra/pull/1733/checks?check_run_id=1899814880#step:7:1584

Error: 
   0: Access is denied. (os error 5)

Unread Stderr:
   The application panicked (crashed).
   Message:  Opening metrics endpoint listener 127.0.0.1:49752 failed

      1213 │     // Second node is terminated by panic, no need to kill.
      1214 │     std::thread::sleep(LAUNCH_DELAY);
      1215 >     node1.kill()?;

Solution

Also rename the tests - the listener is for the Zcash protocol, but the state, metrics, and tracing are Zebra-specific.

Maybe the Windows CI is slow - I just saw a similar error in the tracing test at:
https://github.com/ZcashFoundation/zebra/pull/1735/checks?check_run_id=1900870121

I think we should change zcash_listener_conflict() to zebra_listener_conflict() here as well.
Also, the comment should refer to increased time by metrics or tracing failures in the windows CI.

[teor2345]

I think we should change zcash_listener_conflict() to zebra_listener_conflict() here as well.

It's Zebra's Zcash network protocol listener port, which can conflict with zcashd's Zcash listener port. Unlike the rest of the ports, which are unique to Zebra. I'm happy to say zebra_zcash_listener_port, but the "zcash" is important here.

I'm going to merge this now, because it's a CI fix, and the feedback was all applied.
