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.
