Here is a bit of 3.1 specifics on top of the suggestion below. In 3.1 you'd
configure a custom Module with providers/factories for everything you need.
Inside the module you'll need to bind DataSourceFactory and
Provider<DataDomain>. Then you create a stack with the custom module:
ServerRuntime runtime = new ServerRuntime("", new MyModule());
And then code your implementations of DataSourceFactory and
Provider<DataDomain>. Inside the later, you'd create a DataDomain with attached
DataMaps and DataNodes.
