Ensure an entity ID allows routing of API call to correct backend

Registered by Henry Nash on 2014-03-06

During IceHouse, we had several proposals (and indeed code ready to merge) that solved the issue of correctly determining the domain and driver for an API call that only contains a user or group ID. This is needed for both multi-backend as well as Federation support. However, the approaches (e.g. either encode the domain into the ID or alternatively have an SQL mapping table) have their pros and cons. We need to settle on our approach and implement.
