Add convenient method for matching absence of query param in a request

[G-Basak]

This pull request adds a convenient method for matching absence of query param in a request.
Usage example :

//after this pull request
verify(
    getRequestedFor(urlPathEqualTo("without/queryParam"))
        .withoutQueryParam("test-param"));

It was possible to verify the same even without this method as shown below, but felt counter-intuitive (given there is already a withoutHeader method).

//before this pull request
verify(
    getRequestedFor(urlPathEqualTo("without/queryParam"))
        .withQueryParam("test-param", absent()));

Looks good to me, because indeed there are without methods and it's just some syntax sugar. Tagging @tomakehurst to get his opinion so that we're aligned on the vision for API sugar

We discussed thing and agreed it is good time to add some good DevX. Will proceed with merges, and thanks!
