Gateway Servlet — entry point for all incoming requests
The gateway servlet is the entry point for all incoming requests. It
is responsible for initializing a heap of objects, and
dispatching all requests to a configured servlet (which is itself a heap
object). The configuration of the gateway servlet is loaded from a
JSON-encoded configuration file, typically located at
~/.ForgeRock/OpenIG/config.json.
