        public static int shakeUp​(java.lang.String string,

        Provide a number between 0(inclusive) and upperLimit(exclusive) for the given string, the number will be nearly uniform distribution.

        e.g. Assume there's an array which contains some IP of the servers provide the same service, the caller name can be used to choose the server to achieve load balance. 

             String[] serverIps = new String[10];
     int index = shakeUp("callerName", serverIps.length);
     String targetServerIp = serverIps[index];
        参数:
        string - a string. the number 0 will be returned if it's null
        upperLimit - the upper limit of the returned number, must be a positive integer, which means > 0
        返回:
        a number between 0(inclusive) and upperLimit(exclusive)
        抛出:
        java.lang.IllegalArgumentException - if the upper limit equals or less than 0
