Enhance log messages for DNSSEC
Issues from wiki:
- Also, add a log message to inform user that it started to sign zone. If the zone is large enough, it appears to hang for a couple minutes without any feedback whatsoever.
- I have signature-lifetime set and each time a resign is triggered for this reason, a strange message pops up:
Zone udp53.me. forced signed successfully.
- I don't think it's forced or anything. - Switch some debug statements into log statements
