Add option to expose the API externally.

[coryschwartz]

We should add an option to the CRD to configure how the API should be exposed.

If the API should be a ClusterIP, then the API will be exposed internally for applicaitons in the same cluster.

If the API should be a Loadbalancer, we should setup basic auth

If the API should be Ingress, we should allow authentication on the ingress controller.
