Mike Macgirvin 35a9b49ed0 allow for multiple pubsub hubs so everything can still work when/if one goes flaky
(Google's hub has been particularly unreliable recently and the symptoms are that
you just stop receiving updates, and/or updates you send are silently dropped and
never delivered). Also add more instrumentation to help debug pubsub issues.
