Rebindable (Entity)
- REBINDING_STATUS sensor -> empty (not rebinding), REBINDING, COMPLETED, FAILED
- getRebindLocationGenerator() -> returns a generator suitable for rebinding this entity
    (where the generator produces a RebindLocation initially, but might also produce json/xml;
    and allow interrogation about whether all descendents etc are rebindable)

RebindLocation {
    /** takes no action but says whether it can rebind */
    boolean canRebind(Entity);
    /** sets config & sensors on entity, returns the locations where the entity should proceed to start
