Connector builder global param settings

[meyerovb]

I've used the connector builder for 2 apis already that had 2 individual api keys (clientid and token or key and passcode) dunno why but api builders love that... anyways it would be great to have the ability to add user configured parameters that would be appended to every request. That way the api key auth would be "token" but I'd have another "clientid" user field in a global single place instead of needing to add it to every single stream.
