Initial support for security groups and their association with servers.
SecGroupRule support in and nominally working.
Merge branch 'openstack_security' into development
Updated dependent package list
Big refactor-- in preparation to make namespaces also provide
references, I factored out the common & neutral aspects of the infra
meta system into a set of base modeling classes, and then pared the
infra module down to just use those facilities. It's a much smaller
class now, and modeling can now be used with namespace.
Added in copyright text, and the actual modeling.py module (don't
understand why it was missed originally).
Currently broken; just turned modeling on in the namespace module, and
various aspects need to get fixed up so that namespace operates
properly. Checking in so that the branch can be moved to my laptop.
