Update salt config for apiserver to support Azure.

Shall I add the grain `cloud: gce` to the default salt scripts, and change around the `if grains['cloud'] != 'azure'` to `if grains['cloud'] == 'gce'`? Or leave as is?
Here is what I'm getting in Azure:

```

jeffm@kubes-master:~$ sudo salt '*' grains.items | grep fqdn
  fqdn: kubes-master
  fqdn_ip4:

  fqdn_ip4:
  fqdn_ip6:

jeffm@kubes-master:~$ sudo salt '*' grains.items | grep hostname
  hostnamef: kubes-minion-1.kube-0b57586.d5.internal.cloudapp.net
  hostnamef: kubes-minion-2.kube-0b57586.d5.internal.cloudapp.net
jeffm@kubes-master:~$ 
```
If there something I can do to poke salt to get the full hostname, that would be great.
