add dns option to master.sh

Update the call to [quickstart.sh](https://github.com/fultonj/oooq/blob/master/master.sh#L27) in master.sh to pass "-e ~/local_dns.yaml" and then clean up [init.sh in tripleo-ceph-ansbile](https://github.com/fultonj/tripleo-ceph-ansible/blob/master/init.sh#L18-L24).
```
$ cat local_dns.yaml 
undercloud_undercloud_nameservers:
  - 10.19.143.247

$
```
