Add baseline test for license with sdk

This change adds a test that includes license modules that are used by
modules which are part of an sdk but which does not yet copy the
license module into the snapshot. It includes the refactoring changes
needed to allow license modules to be used in an sdk test and provides
a baseline against which future changes can be compared.
