[Bug 1382190] Re: LXCs assigned IPs by MAAS DHCP lack DNS PTR entries

[Graham Binns]

Andres and I have discussed this further, and he pointed out that the
LXCs can take a *long* time to start. That would be sufficient time for
us to parse the leases file and update the DNS with a PTR for the new
node (option #3).

I've tested this out locally. The LXC container took ~30minutes to start
from `juju deploy mysql --to lxc:0`, and it acquired an IP address ~5
minutes before the juju agent showed as started. It was another 5
minutes until the mysql unit showed as started.

This is more than enough time for us to create DNS entries for the
container, with a hostname either based on its IP address (e.g. maas-
dynamic-1.maas) or based on the client-hostname field in the lease (e.g.
juju-machine-0-lxc-0-dynamic.maas). The second is more meaningful, but
it's also more code.

Andres and I agreed that this was a better solution than #2 above.
