resolv.conf search path doesn't match the domain for the host

Bug Description

When a machine is deployed, we appear to always give it a search path based on the default domain, rather than the actual domain that the machine is in. As a result, the machine cannot resolve its own hostname (since it becomes $MACHINE_NAME.$DEFUALT_DOMAIN} instead of the actual node.fqdn.

To reproduce (given default domain of "maas"):
1. add a domain "bad"
2. Deploy a machine as "testhost.bad"
3. Login and note thus:
     hostname -f
     hostname: Name or service not known
4. Note also that /etc/resolv.conf has "search maas" instead of "search bad" or "search bad maas"

The short fix is probably to make it say "search bad", with a long-term solution of allowing the search list for the node to be specified by the admin (and always prepending, since that determines the FQDN for the host.)

What we actually do today is search = {sorted list of domains for which maas is authoritative}

Which is wrong in various ways, especially if the domain of the machine doesn't happen to sort first.

The correct solution is "search node.domain {any other domains, sorted for consistency}"
