Prometheus Http Connector

As per documentation, Prometheus Keda Scaler is used to query a specific metric. The value queried is used to scale a target worker pod.
Unlike a message queue - there is no specific message to be consumed with Prometheus Keda Scaler. The logic of what to do in a worker depends on the use case and hard to make very generic except for a small subset of use case.
At this moment I can't think of a strong use case for this but if someone has an interesting use case, we can take this up.
