Bug Description

I have noticed that sometimes, randomly (hard to duplicate deterministicaly but easy to duplicate), the MAAS pod compose API call creates machines with duplicate node_id's.

Calling:

$ maas admin pod compose <pod_id>

multiple times on an RSD pod with multiple resources will sometimes create two machines with the same node_id.
