local invoke vs. nested stack function using layer

[mbradburn]

Describe your idea/feature/enhancement

I think from reading this PR: #2760 .. that it's a known issue in the sam cli that you can't pass a layer reference as a parameter from the top-level stack to a function in a nested stack for the purposes of sam local invoke; you get a "Layer is an Invalid Layer Arn" error.

It would be deluxe to be able to define a layer in the top-level stack, share that layer with functions in nested stacks, and also be able to use sam local invoke for testing. Is support for that on your roadmap at all?

Additional Details

I put a sample project at https://github.com/mbradburn/sam-nested-layer in case I'm unclear in my description of the issue.

@mbradburn sorry for delayed response and thanks for the feature request. We have a roadmap here, but we also try to take in popular feature requests based on 👍🏽 from the community. We will be adding this to our intake for prioritization.
