Add instance actions for Live Migration operations

Registered by John Garbutt on 2014-01-06

Currently live-migrate errors are not recorded, so its hard to see what has happened in the past.

This blueprint looks to add instance actions for the live-migrate issues. Importantly:
* record when a live-migrate starts
* record when a live-migrate succeeds
* record when the live-migrate checks fail, or the live-migrate fails

There are no additional APIs, only extra actions with the event_name "live_migrate".
