Code Issues Proposed changes

A functional libvirt + nova_compute + nova_network

Browse Source 
This imports sdakes' nova-docker codebase to show that atomic upgrades
work atleast with nova networking.  This has many corrections.

For more details read:

Implements-blueprint: blueprint libvirt-container
Partially-implements; blueprint container-set-compute-operation-nova
