Minor logging additions

- Clearly mark local and remote discovery start, to make this searchable
even without --logdebug.
- Promote two messages from debug to info: The 'N entries read from db'
message is useful and the 'read from db but ignored' message is rare
and surprising - if there's a bug there we want to see what happened in
the logs.
