Add ability to name listener threads

[onobc]

NOTE: Below description directly cloned from spring-projects/spring-kafka#2501

Summary

Currently listener thread names are set by the task executor; by default, a SimpleAsyncTaskExecutor is used, with thread names

<beanName>-C-<m>-<n> where <beanName> is usually the listener Id, <n> is an incrementing integer, and <m> is the index of the child container.

Add an option to supply a thread name, based on the container, with the default returning the container's listenerId. For child containers, this is the parent listener id + -<m>.

Motivation

Project Loom virtual threads have no name by default; making it difficult to correlate container activity in logs, when there are multiple containers.

I see this is not done yet.

Any thought why do we need to do this since there is that VirtualThreadTaskExecutor from SF?

Thanks

Agreed. I was planning on closing this once I verified this is not needed due to VirtualThreadTaskExecutor.

Closing based on previous comment.

Adding for traceability: spring-projects/spring-boot#36321.

I'm not sure yet what we will decide in Spring Boot, but having a hook for setting a custom VirtualThreadTaskExecutor with desired thread name prefix should be enough as it always was from existing API.
