REP-480 Rate Limit RegEx on Query String

So I'm not certain if getParameterMap() handles decoding or not. I'd like to make sure that's covered in functional tests, and if they fail, we'll have to handle the decoding ourselves.
If they don't specify any parameters to match on, we will always consider the request to match. So yes, we won't care what the passed in query parameters are. In other words, if no query parameters are set in the config, the limit will match as it did prior to these changes.

Did I misunderstand anything?
