**Description**
Allow customers to delete multiple or all function versions and layer versions at once. Support a "max versions" qualifier to automatically delete older function and layer versions when creating a new version.

**Additional context**
1. How would you use these features (for example, via API, CLI, SDK, CloudFormation)?
2. How would you want to handle dependencies for example, would you want to automatically delete function versions associated with a specific layer version?
