**Description**
Automated Dependency Management in Lambda, allowing developers to deploy Lambda directly from source without manual dependency bundling. This will allow customers to deploy ZIP files containing their source code and dependency specifications (package.json, requirements.txt) without manually bundling dependencies. Lambda will automatically import and install dependencies at deployment time

**Additional context**
1) How do you currently build your Lambda functions?

2) When code or dependencies change, how do you ensure your Lambda gets updated correctly?

3) Where is your Lambda function source code primarily stored?

4) Which languages/runtimes would you most want auto-dependency management support for?
