   ### One-line summary [问题简述]
   
   建议itemStyle的borderColor也可以与color一样引入函数动态计算
   
   
   
   ### Version & Environment [版本及环境]
   + ECharts version [ECharts 版本]: 4.2.0-rc.1
   + Browser version [浏览器类型和版本]: chrome
   + OS Version [操作系统类型和版本]: win8, mac
   
   
   
   
   
   ### Expected behaviour [期望结果]
   
   itemStyle的borderColor可以与color一样引入函数动态计算每一项的borderColor值，甚至borderWidth也一起实现可以动态的根据每一项value的值来动态设置可变值，其实感觉itemStyle的每一项配置都可以引入函数配置的方式，更加的灵活自由

               itemStyle: {
                   color: function(...args) { },
                   borderColor: function(...args) { },
                   borderWidth: function(...args) { }

               ...
