* @property {number} maxAttempts
* The maximum number of times the request should be attempted.
* @property {number} baseDelay
* The delay before the first retry, in milliseconds.
* @property {number} backoffFactor
* The multiplier for successive retry delays.
* @property {number} fuzzFactor
* The maximum amount of fuzz to apply to each retry delay.
* For example, 0.5 means "between 50% below and 50% above the retry delay."
* @property {number} timeout
* The request timeout, in milliseconds. Zero means "unlimited".

* @description
* Defines a network request. This is passed to one or more request filters

* @property {string} method
* The HTTP method to use for the request.
* @property {ArrayBuffer} body
* The body of the request.
* @property {!Object.<string, string>} headers
* A mapping of headers for the request. e.g.: {'HEADER': 'VALUE'}
* @property {boolean} allowCrossSiteCredentials
* Make requests with credentials. This will allow cookies in cross-site
* requests. See <a href="http://goo.gl/YBRKPe">http://goo.gl/YBRKPe</a>.

* @description
* Defines a response object. This includes the response data and header info.
* This is given back from the scheme plugin. This is passed to a response
* filter before being returned from the request call.
*
* @property {string} uri
* The URI which was loaded. Request filters and server redirects can cause
* this to be different from the original request URIs.
* @property {ArrayBuffer} data
* The body of the response.
* @property {!Object.<string, string>} headers
* A map of response headers, if supported by the underlying protocol.
* All keys should be lowercased.
* For HTTP/HTTPS, may not be available cross-origin.
* @property {(number|undefined)} timeMs
* Optional. The time it took to get the response, in miliseconds. If not
* given, NetworkingEngine will calculate it using Date.now.
* @property {(boolean|undefined)} fromCache
* Optional. If true, this response was from a cache and should be ignored
* for bandwidth estimation.
