Public bug reported:

"live_migration" call in Liberty doesn't have backwards compatibility
with Kilo.

Liberty control plane and Kilo compute nodes.

Doing live-migration and getting error below on compute node

TypeError: live_migration() got an unexpected keyword argument
'migration'

Workaround(On controller): http://paste.openstack.org/show/495612/

Environment
==========
Libvirt+KVM, Ceph for VMs
Liberty - Mirantis OpenStack 8.0 (2015.2)
Kilo - 2015.1.3 tag

Steps to reproduce
===============
1) Install Liberty control plane (api, conductor, schduler, etc.)
2) Install Kilo compute
3) Add to nova.conf on controller
  [upgrade_levels]
  compute=kilo
3) Try "nova live-migration VM"

Expected result
=============
Migration will succeed

Actual result
==========
Traceback on compute node
http://paste.openstack.org/show/495541/
