optimize curvebs rapid leader schedule

[wu-hanqing]

In order to test the maximum performance of the cluster, it is necessary to ensure that the number of leaders on each process is as consistent as possible. Currently, we provide a command rapid-leader-schedule to accomplish this.

https://github.com/opencurve/curve/blob/5e89a861764d68190d4a81f3746cc447cd014619/src/tools/curve_tool_main.cpp#L63

But in the process of using it, we found that occasionally we need to execute the command multiple times or wait for a long time to make the number of leaders as consistent as possible.

Therefore, we need to optimize the tool so that it only needs to be executed once, and the balance can be completed in a very short time.
