Adds replicas to Contour API type

[danehans]

• Makefile: Set v1 as the CRD version to support CRD defaulting.
  api/v1alpha1/contour_types.go: Adds spec.replicas and status.availableReplicas fields to the Contour API type.
• config/crd/bases/operator.projectcontour.io_contours.yaml: Generated CRD updates from changes to api/v1alpha1/contour_types.go.
  config/samples/operator_v1alpha1_contour.yaml: Removed example foo field. Note that {} is required since spec can not be null.

$ kubectl describe contours does not describe the API. Does anyone know the magic sauce to get the CRD info displayed?

[jpeach]

Should we really add validation to status (i.e. users don't need validation feedback on this)?

(though this particular validation seems fine)

[danehans]

Commit 0c03a81 removes the validation for availableReplicas.

You have to add a shortName field to +kubebuilder:resource

You have to add a shortName field to +kubebuilder:resource

@jpeach I see the shortname:

$ kubectl api-resources | grep contour
contours                                       operator.projectcontour.io     true         Contour
$ kubectl get contours
NAME             AGE
contour-sample   3h17m

I did not have an instance of the contour CR when I ran kubectl describe. It works as expected now:
