Pawel Koniszewski 0c0f60031a Add new configuration option to turn auto converge on/off
Since QEMU 1.6 and Libvirt 1.2.3 it is possible to use auto
converge during live migrations. This option helps to live migrate
instances with memory-intensive workload by throttling down CPU
on guest machine.

Partially-implements: blueprint auto-live-migration-completion

features:
- New configuration option live_migration_permit_auto_converge
has been added to allow hypervisor to throttle down CPU of an
instance during live migration in case of a slow progress due
to high ratio of dirty pages. Requires libvirt>=1.2.3 and
QEMU>=1.6.0.
