[App/Feature] HTTP Queues

[hhsecond]

What does this PR do?

Introducing HTTPQueues to Lightning. This brings in the new HTTPQueue class and the HTTPClient classes. It also makes changes to the cloud dispatcher to pass the queue type. The queue type is defaults to "redis" but for those who wants to use HTTPQueue can set the environmental variable for that. Once the HTTPQueue is stabilized, we'll swap the default to HTTPQueue
