Refactor RPC module loading to util

Code for requiring the api service modules (from in tree) was factored
out into utility code and is not longer part of the rpc code.

Jira-issue: WP-573
Self registering API modules

Add support for API modules that can register one or more RPC services
themself. Modules need to export a "Module" constructor which will be
instantiated by the PZP. "Module" instance are required to have "init"
instance method. This method takes two parameters, a register function and
an unregister function which can be used by the module to register
instantiated RPC services.

This allows API implementations to decide on their own whether to register
a service or not, depending on platform or environment.

Short example for a module implementation:

var MyModule = function(rpcHandler, params) {
	this.rpcHandler = rpcHandler;
	this.params = params;
};

MyModule.prototype.init = function (register, unregister) {
	// instantiate my RPC service, implementd elsewhere
	var service = new MyService(this.rpcHandler, this.params);
	register(service);

	// maybe at some later point in time
	unregister(service);
};

exports.Module = MyModule;

functions to use the same code.
