- Run the Weave integrations regardless of if weave is detected. - Make everything backoff and not spam the logs. - Add miekg dns to vendor. - Have the app periodically register with weaveDNS, and the probe do lookups there. - Decide what the local networks are at runtime, not once at startup. - Correctly resolve app ids, fixes #825
