Improve the target side flow to reduce downtime as of below. - Support reading an optional record which includes the expected stop_copy size. - Once the source sends this record data, which expects to be sent as part of the pre_copy flow, prepare the data buffers that may be large enough to hold the final stop_copy data. The above reduces the migration downtime as the relevant stuff that is needed to load the image data is prepared ahead as part of pre_copy.
