説明

Today we reuse containers for performance reasons. There are many advantages however to run-once that disables container reuse. Just as @tysonnorris is adding support for intra-container concurrency via an opt-in annotation, we can do the same to prevent container reuse for an action annotated accordingly to create a new container every time. This has the nice property of ensuring that every function starts from the same pristine environment.

調査方針: The issue requests a run once mode that disables container reuse, inspired by the annotation based approach for intra container concurrency. A newcomer should explore the container lifecycle management in OpenWhisk's invoker component (e.g., `ContainerProxy`). Review the existing annotation mechanism for concurrency to understand how to add a similar annotation for container reuse. Look at linked PRs or comments for context, particularly the work by @tysonnorris. The implementation likely involves modifying the container creation logic to skip reuse when the annotation is present.
