[New-bugs-announce] [issue31357] Expose `worker_target` and `workitem_cls` as arugments to customize `ThreadPoolExecutor` behaviour

[SenbinYu]

New submission from SenbinYu:

With the two arguments, we can esaily to customize behaviour when I submit task to a ThreadPoolExecutor instance. It's more useful when I want to execute coroutine function with this executor.


With this, we can run coroutine in any pattern programs and don't care about whether the main framework supports. Also, in mamy non asynchronous web application, we can use asyncio releated features in this way. I think people will like this. Although, I can write an another ThreadPoolExecutor, but I think we should reuse as more code in standard lib as we can. Lastly, this makes ThreadPoolExecutor more flexible.
