Add in KeyinCode 3000 series lock integration

Remotelock stopped selling the LS-5i lock that integrates directly with Hospitable, they only sell the KIC Koreline 3500 series that has the same look/features that is managed by Remotelock. To use the same systems that Remotelock offers, we only have the option to integrate Airbnb with this lock, instead of through Hospitable which would include all other platforms.
