migration/dirtyrate: implement dirty-ring dirtyrate calculation
use dirty ring feature to implement dirtyrate calculation. introduce mode option in qmp calc_dirty_rate to specify what method should be used when calculating dirtyrate, either page-sampling or dirty-ring should be passed. introduce "dirty_ring:-r" option in hmp calc_dirty_rate to indicate dirty ring method should be used for calculation.
