Admin: usability

[matzf]

The admin interface is currently barely usable.

Issues:

• no button to add link from an ASes detail page
• border router display string is only DB index
• list of Links is too long and cannot be filtered nicely
  • filter from or to
  • exclude user ASes
• list of Hosts is too long
  • managed only / exclude user ASes
  • filter by configuration deployed / not deployed
• Add link:
  • host selection is huge list, not ordered
  • should be able to select BR for interfaces
  • should verify interface public IP:port is not in existing ones
• Deployment (no longer applicable, push deploy has been removed)
  • no indication of success/error after runningTrigger deployment action. Improve e.g. by adding view that lists pending tasks in queue.
  • no way to see log without sshing to coordinator (or machine)
  • manually set/unset host requires deployment
