move already deployed service to new vps with different ip address.

[John Meinel]

So if the machines are able to contact the API server, they should inform
it of their new addresses, which should update the other charm to point at
the new addresses.
Note that with LXC you'd also have stable IP addresses for mysql and
wordpress in their respective containers.

(This might require 1.21, but I thought the IP address update changes
landed in 1.20)
