Implement RejectUnknownQueryParameters (Fix #660)

[wolveix]

Hello again!

This PR implements an opt-in config option to reject unknown query parameters (fixes #660).

I'm not confident that this is the best way to achieve this, and I'm not particularly a fan of adding an additional function to the API interface definition; however, I couldn't find a better way to achieve this given that this check needs to happen in the Register function which doesn't have access to api.config.
