feat: add InvokeSimpleWithRawParam for multi params with same key name

[alswl]

InvokeJob did not support multi params with same key name. For example, in my case:

	APPLICATIONS	demo-kustomize
	CLUSTERS	sigma-foo,sigma-bar

This will be allowed.

But in the original source, InvokeJob using the map to holds params, that will not support multi params with same name.

The HTTP protocol support multi value with same name. eg:

https://en.wikipedia.org/wiki/Query_string

Jenkins also support multi params with same name,

My solution is add InvokeSimpleWithRawParam to support raw url.Values, this class support using Add() add multi values with same name.
