[libvirt] [PATCH test-API 0/2]Use encapsulated python APIs in testcases

[Guannan Ren]

These two patches modify library modules and exsiting testcases for
disallowing the use of the objects of subclasses in libvirt.py directly.
The files in lib directory are the layer of encapsulated python APIs. we
should use methods in it for good error catching.
