feat: add NewJsonResponseOrPanic function to simplify calls with ResponderFromMultipleResponses

[kilianpaquier]

Simplify calls to ResponderFromMultipleResponses for JSON body responses with NewJsonResponseOrPanic.

Just as the same as NewJsonResponderOrPanic and NewJsonResponder, it's an addition to simplify some calls and avoid local variables with error handling.

Thanks for your PR. See my comments to go further.

Just as a note did you know that you can chain Responder using Then method? It appeared after ResponderFromMultipleResponses implementation. Using it you can do:

responder := httpmock.NewJsonResponderOrPanic(200, x).
  Then(httpmock.NewJsonResponderOrPanic(200, y)).
  Then(httpmock.NewJsonResponderOrPanic(200, z))

Hi, yes I did see this builder function. We've been using it for the last two days, it's great too !

But I still think that NewJsonResponseOrPanic could be a useful addition, what do you think ?
