Lambda JS files should move to a subdirectory

[ruurtjan]

Current situation:
Javascript files for Lambda functions (and probably any lambda source file) are in the root of the generated zip file. Calling aws cloudformation package causes each Lambda to include all files in the root directory, including .git and .idea directories. Uploads take longer than necessary and contain data that shouldn't be in there.

Feature request:
Move each Lambda file to its own directory and reference that in the Cloud Formation template when generating a zip file for download.
