ONOS-4971: Synthetic Link Data -- WIP

- Breaking out UiLink to subclasses for device links, host links, region links, region-device links,
    - (soon, also peer links).
- Augmenting UiLinkId to include regions as endpoints.
- Introduced UiSynthLink to encapsulate synthetic links bound to regions.
- Model Cache now computes synthetic links from the underlying link data.
- Added endPointA/B() and type() methods to UiLink.
- Updated topo2CurrentRegion response to include synth-links for the region.
