enhance detail: add an option parameter(-p) to invoke command,make it possible to call methods with complex parameter types.
for example:

1. we can use "invoke org.apache.dubbo.demo.provider.test.OverrideService.student({"name":"zhangsan", "age":12}) -p org.apache.dubbo.demo.provider.test.Student" to call a method with signature of “public void student(Student student)”
2. we can also use "invoke org.apache.dubbo.demo.provider.test.OverrideService.student({"name":"zhangsan", "age":12}, {"schoolName":"hello"}) -p org.apache.dubbo.demo.provider.test.Student org.apache.dubbo.demo.provider.test.School" to call a method with signature of "public void student(Student student, School school)"
   3.if -p is not specify, the result is the same as the previous version
