[Bug 1030860] Re: Maas-hosted DNS is not enabled.

[Andres Rodriguez]

** Description changed:

  To enable DNS we need to:
- - make sure that bind9utils dnsutils bind9 python-netaddr are installed (new dependencies)
+ - make sure that  bind9 (Installs bind9utils) python-netaddr are installed (new dependencies)
  - make sure that the directory /etc/bind/maas (etc/celeryconfig.py:DNS_CONFIG_DIR) is created
  - call `sudo maas set_up_dns` (this will create an empty [i.e. no DNS zone] configuration with the required rndc key in etc/celeryconfig.py:DNS_CONFIG_DIR : /etc/bind/maas)
- - add the result of `sudo maas get_named_conf` to named.conf.local
+ - add the result of `sudo get_named_conf` to named.conf.local
  - restart bind9
  
  How to test this:
  $ sudo maas shell
  from django.core.management import call_command
  from maasserver.models import DHCPLease, NodeGroup, Node, MACAddress
  # Create the master nodegroup, jtv is fixing the code to get that done as part of a migration
  call_command('config_master_dhcp', subnet_mask='255.255.0.0', broadcast_ip='10.111.255.255', ip_range_low= '10.111.123.9', ip_range_high= '10.111.244.18', router_ip='10.111.123.9')
  # At this stage, the zone is defined and all the auto-generated hostname are in place:
  # dig @127.0.0.1 10-111-123-9.master +short
  
  # Create a node in that nodegroup. Its hostname is 'myhostname'
  master = NodeGroup.objects.get(id=1)
  node = Node(hostname='myhostname', nodegroup=master)
  node.save()
  mac = MACAddress(node=node, mac_address='11:22:33:44:55:66')
  mac.save()
  # Create a lease for that node:
  DHCPLease.objects.update_leases(master, {'10.111.123.10': '11:22:33:44:55:66'})
  # Now the hostname of the node can be queried:
  # dig @127.0.0.1 myhostname.master +short
