 Description   

After a chunk has been chosen to be migrated, we should check if the chunk is greater than the chunk size and if so split it then migrate one of the new smaller chunks. This will make lowering the chunkSize setting start having an impact to migrations much faster than waiting until the chunks are all split naturally.
