In the past you could tell the nodes in a test cluster to attach themselves to a waiting debugger on startup by passing the `--debug-server-jvm` option documented here:

https://github.com/elastic/elasticsearch/blob/c0228c73fea5caf279bf7141eabea50813c4528b/TESTING.asciidoc#L383-L390

I think this changed in #92379 and no longer seems to work. In fact I really wanted to attach a debugger to just one of the nodes in the cluster, and I believe #92379 might make this much easier to use (e.g. maybe via a method `LocalNodeSpecBuilder#debuggerPort(int)`). That'd be even better.
