[GitHub] [pulsar] lifepuzzlefun opened a new issue, #18959: [enhancement][broker] Introduce thread block monitoring mechnism.

lifepuzzlefun opened a new issue, #18959:
URL: https://github.com/apache/pulsar/issues/18959

   ### Search before asking
   
   - [X] I searched in the [issues](https://github.com/apache/pulsar/issues) and found nothing similar.
   
   
   ### Motivation
   
   Although it was an old story that worker threads maybe blocked by blocking operations.
   But for earlier version we still found blocking occurs in our env.
   
   I think we can just `ping` those worker thread to check if the thread is blocking by send a task in the thread task queue.
   If thread is blocking for long time, `ping` task won't be executed. so we can add an alart to notify us potential thread blocking and restart the process.
   
   This complete the current mechnism, 
   current we only have thread task queue size, complete task number by enable task tracing. 
   but they are diffcult to set an alart to justify the blocking condition and only support `OrderedExecutor`.
