Does this need anything else, @stevezau @frankreno ?

@AlexB138 : First off thank you for the PR. This looks good. However, I am wondering if we should have 2 YAML files. One with RBAC, one without. That would be more in sync with a lot of the YAML files provided by k8s in their docs. Thoughts?

[AlexB138]

Yeah, I've seen a couple of projects do that as well. I think the way to do it is to have them in separate directories. I say this because doing kubectl apply -f <directory> is a common workflow for provisioning and having two yaml files in the same directory with different configs for the same resources would break that pattern.

I'll update the PR to have /daemonset/rbac/fluentd.yaml and daemonset/nonrbac/fluentd.yaml, if that works for you.

[frankreno]

That sounds great.

@frankreno Alright, broken out as discussed and updated the README!
