A validator that is still running its first validation answers a query
with No Data Available (error code 2). That ended the session, and the
next attempt came after the retry interval: 600 seconds when the cache
had not yet said otherwise, which it cannot have before it has data.
For those ten minutes after a validator started, nothing was validated.
No Data Available is now asked again after 30 seconds, or after
retry_seconds if that is shorter, and logged as information rather than
as a warning. Other failures wait as before, after trying the next
cache if there is one.
