The expectations about level come from syslog:

       LOG_ERR        error conditions

       LOG_WARNING    warning conditions

       LOG_NOTICE     normal, but significant, condition

       LOG_INFO       informational message

       LOG_DEBUG      debug-level message

Therefore messages where an API did something wrong should be NOTICE
and messages where an API's normal action was successful should be
INFO or DEBUG.

All the "already XXX" messages should be NOTICE.
