        Create a dict with names of available services and classes that
        implement them.

        This is a recursive function since __subclasses__() only returns direct
        subclasses. If class A(object):, class B(A):, and class C(B):, then
        A.__subclasses__() doesn't contain C.

        All subclasses of the Service class are saved in the `services`
        dictionary. It is intended that each of these was imported by the
        _import_services function, but this is not enforced. The key in the
        dictionary is the `name` class-level field, and the value is the class
        itself. It is recommended that the service "example" be implemented
        in a class "ExampleService" defined in a module named
        "example_service", but this is not enforced, and the only string
        visible to the end-user/analyst is the service name.
