This is refactoring in the lead up to passing mutual TLS certs for helm applications. As such we expect all applications to need config files so we can remove the logic about which applications need and do not need this (ie `#config_map?`).
This was causing a spec failure between Gitlab::Kubernetes::Helm::Pod and
Gitlab::Kubernetes::Helm::Api::Pod if one spec loaded the former
definition first.
