New resource specification for EnvoyConfig custom resources

[roivaz]

This PR changes the way that resources are specified in the EnvoyConfig custom resource. A new field spec.resources has been added that is meant to replace spec.envoyResources. Both fields and specification formats work currently, with the controller internally transforming from spec.envoyResources to spec.resources.

The new resource specification looks like this:

apiVersion: marin3r.3scale.net/v1alpha1
kind: EnvoyConfig
metadata:
  name: test
spec:
  nodeID: test
  resources:
    - type: listener
