Support a set of response for the same kind of requests

[27149chen]

Like the python mock, I can set a list of responses in this way: say_hello.side_effect=["h1", "h2"], and first call will return "h1", while second call will return "h2". Is it possible to do it in gripmock?

for now I don't it's possible. since we are based on Go. But I will put that for future development
