seems like there's no reason to make this a class, since all it does is declare
two types and provide a static method. Remove the class and move the
declarations directly into the policy namespace?

Okay, I've removed the class and renamed this file to
configuration_policy_handler_list.h. I couldn't find a good place to include
this anywhere else.
