SQS Infinite Loop with Empty Entitlements

[fernando-mc]

Describe the bug

When the AWS Marketplace service returns empty entitlements the application errors and is thrown into an infinite loop.

To Reproduce
Steps to reproduce the behavior:

You can test this with an event that has empty entitlements:

For a simple example. Comment out this line in entitlement-sqs.js:
const entitlementsResponse = await marketplaceEntitlementService.getEntitlements(entitlementParams).promise();

And replace it with something like:

const entitlementsResponse = {'Entitlements': []}

Then, trigger the function.

4. The function will error as shown in the screenshot (Which happened because a response from AWS in that structure was returned when actually calling the entitlements service).

Expected behavior
Either the marketplace service API call doesn't return an empty entitlement, OR a DLQ and better error handling is added to this application so that events like this are sent to the DLQ instead of being retried.
