把两个数组连接成按从小到大的一个数组例如：
var allowVlan = '23-25,45,4-6,67,50-53';
var unTagVlan = '1-5';
完成时应该是1-6,23-25,45,67,50-53；
本例中用到了数组的方法：
1.数组连接
2.数组包含，
3.数组排序
4、数组去重
备注：listCombinationStr 函数中包括字符串组成list 比如，[1,2,3,5,6,9] ===>>1-3,5-6,9这种形式，getStrCollationPort是强调了下这种形式

自己测试了没有什么问题，如果看到的人有什么新的思路，或者其他好的方法，欢迎来踩，一起讨论
