Helm chart does not work well with "helm template"

[valorl]

Currently, most of the templates omit .metadata.namespace.

This works fine with helm install / helm upgrade where all the manifests without a namespace will be installed to --namespace anyway.

However, helm template will produce the manifests as-is (with no namespace), regardless of --namespace, forcing users to add the namespace manually, or use additional tools on top like kustomize.
