Description

In PR #48398, which fixes memory leak issues with associations by container.id, we implemented the fix under the assumption that PodIdentifiers are unique and maps to a single pod, as discussed in this thread.

However, looking at the implementation of config.Validate(), there doesn't seem to be any check currently enforcing or verifying this uniqueness.

I am opening this issue following this PR comment to address this missing validation.
