 /**
 * Guzzle node.js test server to return queued responses to HTTP requests and
 * expose a RESTful API for enqueueing responses and retrieving the requests
 * that have been received.
 *
 * - Delete all requests that have been received:
 *      > DELETE /guzzle-server/requests
 *      > Host: 127.0.0.1:8125
 *
 *  - Enqueue responses
 *      > PUT /guzzle-server/responses
 *      > Host: 127.0.0.1:8125
 *      >
 *      > [{'status': 200, 'reason': 'OK', 'headers': {}, 'body': '' }]
 *
 *  - Get the received requests
 *      > GET /guzzle-server/requests
 *      > Host: 127.0.0.1:8125
 *
 *      < HTTP/1.1 200 OK
 *      <
 *      < [{'http_method': 'GET', 'uri': '/', 'headers': {}, 'body': 'string'}]
 *
 *  - Attempt access to the secure area
 *      > GET /secure/by-digest/qop-auth/guzzle-server/requests
 *      > Host: 127.0.0.1:8125
 *
 *      < HTTP/1.1 401 Unauthorized
 *      < WWW-Authenticate: Digest realm="Digest Test", qop="auth", nonce="0796e98e1aeef43141fab2a66bf4521a", algorithm="MD5", stale="false"
 *      <
 *      < 401 Unauthorized
 *
 *  - Shutdown the server
 *      > DELETE /guzzle-server
