Missing feature to execute resource initializer from facade

[dbeuchler]

Is your feature request related to a problem? Please describe.
We want to auto install our application and want to execute a resource initializer from outside the resource management module.
There is no possibility to execute an initializer on the ResourceManagement-Facade (compare to execute product importer).

Describe the solution you'd like
A new method ExecuteInitializer(IResourceIntializer initializer);

Describe alternatives you've considered
There is a workaround to get the ResourceGraph by reflection.

var resourceInitializer = new MyResourceInitializer();
var resourceGraph = ResourceManagement.GetType().GetProperty("ResourceGraph").GetValue(ResourceManagement, null) as IResourceGraph;
var resources = resourceInitializer.Execute(resourceGraph);
resources.ForEach(r => resourceGraph.Save(r));
