Add migration parameters to allow the user to adjust the parameters

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.
Marked experimental; do we think it will be promoted to stable before
2.5 is released?
Not a clue :) I have no idea how things move from x- to sans x-.
What happens if I set throttle-initial to 50 and throttle-increment to
50? The previous patch required throttle percentage to be between 1 and
99 inclusive; does that mean I cap out at 99 instead of an invalid
throttle of 100?
The call to cpu_throttle_set will take care of the capping. Details
provided in previous reply :)

We've missed 2.4; these lines need to say (Since 2.5).

# Since: 2.4

Would be nice to document the default (20).

And again (10). Also, same comment about needing 2.5.
I will fix all of these.
