Add AdditionalPrinterColumns to IngressRoute CRD spec

[rosskukulinski]

Fixes #617.

I have tested to ensure that this doesn't break anything for Kubernetes API or kubectl <1.11

Given ingressroutes:

apiVersion: v1
items:
- apiVersion: contour.heptio.com/v1beta1
  kind: IngressRoute
  metadata:
    name: apps
    namespace: default
  spec:
    routes:
    - match: /
      services:
      - name: apps
        port: 80
    virtualhost:
      fqdn: apps.heptio.com
- apiVersion: contour.heptio.com/v1beta1
  kind: IngressRoute
  metadata:
    name: blog
    namespace: default
  spec:
    routes:
    - match: /blog
      services:
      - name: blog
        port: 80
- apiVersion: contour.heptio.com/v1beta1
  kind: IngressRoute
  metadata:
    name: heptio
    namespace: default
  spec:
    routes:
    - match: /
      services:
      - name: kuard
        port: 80
    - match: /blog
      delegate:
        name: blog
    virtualhost:
      aliases:
      - www.heptio.com
      fqdn: heptio.com
      tls:
        secretName: heptio-tls
kind: List
metadata:
  resourceVersion: ""
  selfLink: ""

Getting IngressRoutes results in:

$ kubectl get ingressroute
NAME      FQDN              ALIASES            TLS SECRET   FIRST ROUTE   STATUS    STATUS DESCRIPTION
apps      apps.heptio.com                                   /             valid     valid IngressRoute
blog                                                        /blog         valid     valid IngressRoute
heptio    heptio.com        [www.heptio.com]   heptio-tls   /             valid     valid IngressRoute

This is ready for review, but not critical for 0.6.0-beta3 - OK to leave to 0.6.0
