Implement dirtyrate calculation periodically basing on dirty-ring and throttle virtual CPU until it reachs the quota dirty page rate given by user. Introduce qmp commands "set-vcpu-dirty-limit", "cancel-vcpu-dirty-limit", "query-vcpu-dirty-limit" to enable, disable, query dirty page limit for virtual CPU. Meanwhile, introduce corresponding hmp commands "set_vcpu_dirty_limit", "cancel_vcpu_dirty_limit", "info vcpu_dirty_limit" so the feature can be more usable. "query-vcpu-dirty-limit" success depends on enabling dirty page rate limit, so just add it to the list of skipped command to ensure qmp-cmd-test run successfully.
