Take down edge ports on a leaf switch when all uplinks are gone

- Bug fix for case when all uplinks are gone, but dual-homed host continues to send packets to switch;
  We now administratively take down the host port to force the host to use the other leaf in the pair.
- Restructured SR manager by creating a LinkHandler
- fixed/added some log messages
