Description of problem:

In the newest version of libvirt, lxc-enter-namespace is supported by virsh command. But it seems that it's the only way to use it. And there is no API exposed via python layer.

Version-Release number of selected component (if applicable):
The newest version still exists the problem

How reproducible:
Use python to import all libvirt-related packages and see details by dir() function. No whole API for lxc-enter-namespace is provided.



Steps to Reproduce:
1. Use an Interactive python:
import libvirt
import libvirt_lxc
import libvirtmod
import libvirtmod_lxc
2.
dir(libvirt)
dir(libvirt_lxc)
dir(libvirtmod)
dir(libvirtmod_lxc)
3.
search lxc from the output of dir(..) above. 

Actual results:
'lxcOpenNamespace'
'virDomainLxcOpenNamespace'

Expected results:
A whole API for 'lxc-enter-namespace' function is exposed.
