Feature support matrix should list support for force-completing a live migration

[Matt Riedemann]

The feature support matrix has a section for virt drivers that support live migration:

http://docs.openstack.org/developer/nova/support-matrix.html#operation_live_migrate

But the 2.22 microversion added support for forcefully completing a live migration:

http://docs.openstack.org/developer/nova/api_microversion_history.html#id20

However, that's currently only supported by the libvirt driver, and even then only in certain cases, like libvirt>=1.3.3, qemu>=2.5.0, and the VIR_MIGRATE_POSTCOPY flag must be set.

We should, however, document that this is at least an operation people can try to perform via the REST API and describe what it does and which virt drivers support it.
