Check if block migration is running before throttling
guest down in auto-converge way.
Note that this modification is kind of like code clean,
because block migration does not depend on auto-converge
capability, so the order of checks can be adjusted.

Implement dirty-limit convergence algorithm for live migration,
which is kind of like auto-converge algo but using dirty-limit

This commit is prepared for the implementation of dirty-limit
convergence algo.
The detection logic of throttling condition can apply to both
auto-converge and dirty-limit algo, putting it's position
