namespacedNameError on Proxy when attempting to submit a cURL call to it

Nevermind, this wasn't the case. Not sure what the specific issues was here but I've got a good feeling I just made a spelling mistake somewhere and when I re-applied things they fixed themselves. Regardless I spent some time going down a rabbit hole. Couple of learnings for anybody who might stumble on this:

1. DNS may have trouble resolving for the externalName service, always try out the FQDN (i.e. keda-add-ons-http-interceptor-proxy.keda.svc.cluster.local) before trying much else.
2. You may have to define ports in the externalName service as well:

apiVersion: v1
kind: Service
metadata:
  name: my-proxy
spec:
  type: ExternalName
  externalName: keda-add-ons-http-interceptor-proxy.keda.svc.cluster.local
  ports:
  - port: 80
    targetPort: 8080

3. The ALB Ingress Controller does not play nice with the externalName service as of now either, but there is an open PR as of writing this. To get around it, I unfortunately just have to run keda and the http add on in each of my namespaces.
