SQS Queue Policy

[nbarthel]

Summary

I need an AWS::SQS::QueuePolicy.

I noticed that the SNS resource has an associated topic policy and so I have modeled a Jets "core" implementation for AWS Queue Policy (soon to be PR) to match. The SNS topic policy implementation looks incomplete / unused and doesn't have spec coverage, or I'm missing something...

Motivation

I need an SQS queue policy (specialized resource) for Amazon MWS Subscription API integration. MWS uses a specific policy to enable subscription to events from Amazon stores. I'm sure this pattern is used in other places. A generalized AWS::SQS::QueuePolicy resource implementation would be useful to all.

Guide-level explanation

A general implementation of AWS::SQS::QueuePolicy (linked above) modeled after the existing SNS Topic Policy.

Reference-level explanation

Drawbacks

I could implement this as an extension, but it is a core feature and would be a nice addition for others.

Unresolved Questions

Extension or core? Does SNS Topic Policy work now? Where should I add a spec for this?
