Add namespace to templates

[rasebo]

Adding namespaces to templates in order to avoid having objects deployed to the default namespace in certain deployment scenarios.

@rasebo I'm not familiar with Helm, but wouldn't you set the namespace with the CLI?

It can be, but this chart can also be used as a subchart, in which care you can end-up with a more complicated setup, where you might have some resources deployed to different namespaces, as part of the same parent chart.

In that scenario, it's a good idea to have all manifests specify the namespace where they can be deployed onto because a kubectl -n my-namespace apply -f would generate conflicts.

Thanks for the PR!
I think the RBAC template is a bit off (seems like it's always been the case) as cluster-scope resources should not have "metadata.namespace" field. The rest is good :)
