TODOs: Use constant ad and scan to share lists to invited users

While the new Syncbase API is being worked on, we will perform sharing
with Discovery directly.

- constant scan for syncgroups advertised to you
- constant ad for syncgroups you shared with others

Issues:
- Discovery is a little flaky; the shares don't always succeed after the
  first few
- Nexus 9 still likes to crash (because of the CGo pointer problem)
- Discovery doesn't let you make these ads private
  https://github.com/vanadium/issues/issues/1328
- Menu to Share is shown even though the user may only have Read access
  for the todo list syncgroup.
