說明
force being 'nice', imply sleep time per chunk time; range: [0.0..100.0]. Example values: 0 is aggressive. 1: for every 1ms spent copying rows, sleep additional 1ms (effectively doubling runtime); 0.7: for every 10ms spend in a rowcopy chunk, spend 7ms sleeping immediately after
範圍 0.0~100.0，每複製完一個chunk的資料後，
gh-ost 將休眠 複製消耗的時間 * nice-ratio ，當為0時不會休眠
範例：假設每複製一個chunk的資料需要 100ms
當 nice-ratio=0.5 時， gh-ost 將休眠 100*0.5=50ms
當 nice-ratio=2 時， gh-ost 將休眠 100*2=200ms
