migration: disable auto-converge during bulk block migration
auto-converge and block migration currently do not play well together. During block migration the auto-converge logic detects that ram migration makes no progress and thus throttles down the vm until it nearly stalls completely. Avoid this by disabling the throttling logic during the bulk phase of the block migration.
