I'm starting to wonder if it is necessary to store all of the optional keys for a config element on the value itself. Wouldn't it be easier to just store `oae-termsandconditions/termsAndConditions/text/nl_NL` as a column in Cassandra? Inside of the feed that gets the Terms and Conditions for the current user, we can then just ask for `oae-termsandconditions/termsAndConditions/text/default` and `oae-termsandconditions/termsAndConditions/text/nl_NL`.

That would take away the oddities around updating and retrieving config values.
