migration: Parameters for auto-converge cpu throttling
Add migration parameters to allow the user to adjust the parameters that control cpu throttling when auto-converge is in effect. The added parameters are as follows: x-cpu-throttle-initial : Initial percantage of time guest cpus are throttled when migration auto-converge is activated. x-cpu-throttle-increment: throttle percantage increase each time auto-converge detects that migration is not making progress.
