Add UKBA seed data for Transition

This is seed data for the Transition/Bouncer app which is never intended to be served by Redirector.

Transition already has code for importing Redirector data, and this is a reasonable place to put it that decouples data from deploys, allows peer review and avoids proliferation of repositories. It is intended that Transition will one day have UI for creating and editing all of this data, making this redundant. For now, we need seed data for UKBA so that the AKA domains can be tested and used.

There will be small change in Transition to pull data in from this additional directory.
