In SynchronousRestObjectRequester.MakeRequest<TRequest, TResponse>(string verb, string requestUrl, TRequest obj, int pTimeout, int maxConnections) actually set timeout on WebRequest if given.

Previously, we were doing nothing with this parameter.
No effect on current code since none of the 6 callers attempt to use the timeout.
minor: Add method doc to SynchronousRestObjectRequester.MakeRequest() methods
