Ability to set the withCredentials for cross-domain calls on the player

Created by: kbunge

Currently the only way to to have the withCredentials boolean set on a request to a PlayReady license service is to attach a protection data array and pass in a bearerToken. I have a licensing service that doesn't require the bearerToken to be set as the Authorization header and instead just need to have the withCredentials boolean set to true as the cookies already exist in the browser to handle the authorization to the license service. Can an option be added to just allow the withCredentials boolean to be set to true?
