Add a MQ Server support for Azure Storage Queues
Storage Queues are cheaper and more performant than azure service bus if guaranteed first-in-first-out, etc is not required.
They do offer 'At-Least-Once' guaranteed delivery, where Redis is 'fire and forget'.
Combining this with full featured CosmoDb caching instead of Redis would make a compelling low-cost option.

Would love to see this as well considering storage accounts are more prevalent than having to setup Service Bus or Redis.
