Add a ConfigFilter wrapper class to enforce option scoping

Registered by Mark McLoughlin on 2014-06-02

Add a new class designed to wrap cfg.ConfigFilter, with the following use cases in mind:

1. Help enforce that a given module does not access options registered by another module, without first declaring those cross-module dependencies using import_opt().

2. Prevent private configuration opts from being visible to modules other than the one which registered it.
