feat: Add config option for providing AWS account ID for linking

[chynesNR]

Adds the ability to provide an AWS Account ID, which can be used to help link related entities.

This functionality is needed for multiple feature branches which is why I'm merging to main first, even though this won't be used yet.

Looks good to me. I think we just need a few more test updates to increase the patch coverage.

I'm also assuming that the updates to the instrumentation that will use this setting will be handled in separate PRs.

Correct, there are separate tasks for that work and testing
