OSM: Juju models are not cleaned up when removing NS instance #9

I am not sure whether this issue is caused by layer-sshproxy or another part of OSM.

When making some tests with creating and removing NSs with VNFs using Charms, I noticed that at least sometimes the Juju models do not get cleaned up:

$ juju list-models
Controller: osm

Model                                  Cloud/Region         Type  Status     Machines  Units  Access  Last connection

The setup here is just running one NS with one VNF instance, but the old Juju models created for already-deleted NS/VNF instances seem to not get disposed. Tested with OSM ReleaseSEVEN.

It's unrelated to sshproxy, but it might be related to bug 969. Please comment there if that's relevant to you, or file a new bug if not.

Thanks!
