Utility method to process the webhook notification from HttpServlet#doPost.
The HttpServletRequest#getInputStream() is closed in a finally block inside this
method. If it is not detected to be a webhook notification, an HttpServletResponse#SC_BAD_REQUEST error will be displayed. If the notification channel is
found in the given notification channel data store, it will call UnparsedNotificationCallback#onNotification for the registered notification callback method.
