Rke: Support for configuring cloud-provider

[de13]

I ask while I trying to figure out where to set the option:

  kube-controller:
    image: rancher/k8s:v1.8.3-rancher2
    extra_args: {--cloud-provider=aws}
[...]
  kubelet:
    image: rancher/k8s:v1.8.3-rancher2
    extra_args: {--cloud-provider=aws}
    cluster_domain: cluster.local

@de13 currently with RKE we explicitly set cloud provider to empty value for all k8s components because in order to enable cloud providers we have to configure each provider's options separately, we plan to include multiple cloud providers soon to RKE.

Also to enable extra args you don't need -- you can just do that:

extra_args:
  arg: value

It was my second guess, but doesn't work:

extra_args:
  cloud-provider: aws

Any roadmap for this implementation?

431 and #414 both enable cloud provider support now. (verified)

Tested and confirmed working in #434
