Keqian Zhu dc14a47076 migration/throttle: Add throttle-trig-thres migration parameter 
Currently, if the bytes_dirty_period is more than the 50% of
bytes_xfer_period, we start or increase throttling.

If we make this percentage higher, then we can tolerate higher
dirty rate during migration, which means less impact on guest.
The side effect of higher percentage is longer migration time.
We can make this parameter configurable to switch between mig-
ration time first or guest performance first.

The default value is 50 and valid range is 1 to 100.
