Fix and improve logging for runtime object sync 

config::UpdateObject would create a new object, but this may
have been silently ignored with 'ignore_on_error' - downtimes, etc.
Since we cannot simply fetch the error from inside the config compiler,
we'd just check whether there's a config object created at this stage.
This happens synchronously, and once there is, log something.

The previous code always logged the creation, even if the downtime
was ignored, e.g. when the first master sent one for local host objects.

This commit also adds more details: identity, endpoint, zone to extract
the MessageOrigin details into log messages for better troubleshooting
and debugging.
