Keda: Unable to use RabbitMQ target. Issue parsing RabbitMQ host.

[PixelRobots]

When trying to use this with RabbitMQ I am unable to create the HPA. It seems it has issues parsing rabbitmq host. I have tried it as a secret and also hardcoded into the yaml file. Fresh cluster running newest version of Keda.

Expected Behavior

connect to rabbitMQ cluster and create HPA

Actual Behavior

Unable to connect to rabbitMQ cluster and unable to create HPA.

Steps to Reproduce the Problem

1.RabbitMQ cluster running in AKS

1. Deployment created that I want to scale.
   3.Apply yaml file to create HPA

Specifications

• Kubernetes v1.14.8
• AKS
• RabbitMQ

Good to see the issue was resolved, can we improve the docs around this to help you in the future?

I'd love to know how this was resolved too as I'm getting the same issue with hardcoded and with Secret B64 encoded
