zip S3

[relly]

When we deploy a nodejs action through Backand CLI we upload all the local folder content into S3. Then we call to an action in ORM to zip all the content in S3 folder and to create or update a Lambda. The S3 package that we use fails with large amount of files.
Either fix or find a replacement.
The zip takes place at /lambda/update_lambda_function.js and /lambda/create_lambda_function.js
you can test at /test/lambda_test.js

1. Test and see that it works with small sizes
2. Test and see that it fails with large
3. See how it maintains the folder structure inside the zip file by download it and unzip it. This is important because it is not a zip that runs on a file system, it runs on S3.
