Code Issues Proposed changes

Add libvirt config classes for handling capabilities XML doc

Browse Source 
Libvirt exposes the host/hypervisor features using an XML
schema known as "capabilities". Currently the libvirt driver
code just parses this in an adhoc manner using xpath queries.

This change provides a handful of classes LibvirtConfigCaps,
LibvirtConfigCapsHost and LibvirtConfigCapsGuest for maintaining
an object based representation of the capabilities. The
LibvirtConfigCapsHost class also uses the existing LibvirtConfigCPU
class

Fixes: bug #1003373
Implements: blueprint libvirt-xml-cpu-model
