rabbitmq scaler unsafeSsl does not work for amqps

[alita-moore]

Report

If you pass in a amqps host to the rabbitmq scalar it will require that the certificate is signed, however if you pass in https instead it works as expected.

Expected Behavior

tls is enabled without validation

Actual Behavior

Warning KEDAScalerFailed 5m49s (x14 over 66m) keda-operator error establishing rabbitmq connection: tls: failed to verify certificate: x509: certificate signed by unknown authority

Steps to Reproduce the Problem

1. install keda and rabbitmq
2. setup a ScaledObject with a config similar to the following

apiVersion: keda.sh/v1alpha1
kind: ScaledObject
metadata:
  name: queue-consumers-scaledobject
  namespace: ml-serving
spec:
  scaleTargetRef:
    name: queue-consumers
  pollingInterval: 5
  cooldownPeriod: 60
  maxReplicaCount: 10
  minReplicaCount: 1
  triggers:
    - type: rabbitmq
      metadata:
        queueName: prod.tasks.image.parsing
        value: "5"
        mode: QueueLength
        activationValue: "1"
        hostFromEnv: RABBITMQ_URL
        protocol: auto
        tls: "enable"
        unsafeSsl: "true"
      authenticationRef:
        name: rabbitmq-trigger-auth

3. start the deployment / scaler
4. notice that it only works if RABBITMQ_URL starts with https instead of amqps
