refactor(authservice): Make .yaml files contain only one type of resource

Bug

Description

Currently, the autheservice namespace.yaml contains a secret, namespace and HelmRelease resource. I was looking for the haproxy helm release, expecting it in haproxy/helmrelease.yaml or authservice/helmrelease.yaml, but it was in authservice/namespace.yaml instead.

Our package requirements state that Helm Packages contain one Kubernetes object definition. Although we did not explicitly state these should apply to Big Bang as well, I think it would be good practice. This means moving the secret and helmrelease out of namespace.yaml into their own files.

BigBang Version

1.0.8
