logging: consider adding startup and shutdown messages
I thought I was having a problem with my kresd.log as it wasn't getting updated. Then I realized mostly only errors get logged there and nothing is printed there on service start or stop. If I did a known bad query I could cause an update there. Please consider log entries on start/stop. I note that kres-cache-gc already does this on startup:
kres-cache-gc[18916]: Knot Resolver Cache Garbage Collector, version 5.5.2
so maybe something similar for kresd, and shutting down messages for both. Thanks
