• simplify querystring building

I don't think this really does the right thing. For example, multiValueQueryStringParameters might have the following value:

    "multiValueQueryStringParameters":{
      "name":[
        "me"
      ],
      "multivalueName":[
        "you",
        "me"
      ]
    }

This corresponds to a url querystring like ?name=me&multivalueName=you&multivalueName=me

If you fed the same data into http_build_query, it would generate the following querystring: ?name[0]=me&multivalueName[0]=you&multivalueName[1]=me. (The square brackets [] would actually be url-encoded, but I left them unencoded to make it easier to understand here.)

Can you double check my thinking?
