Behavior:

Zabbix Server, Proxy, and Agent are tagging their log messages with a far too dramatic severity level. Entries like `executing housekeeper` should not be `warn`, but `info` or even `debug`. Also, e. g. `sending configuration data to proxy` should rather be `info` than `warn`. Also, `item unsupported` entries could also be `notice`.

The negative consequence of these dramatically exaggerated log levels is that it makes it way harder to filter out actually severe problems, not mentioning odd entries like `******************************` which makes kind of sense if it was logging directly to console or to a file, but it's unnecessary, and might confuse people. At least it's not `warn`.

Expected Behavior:

I'd expect RFC 5424 compliant log levels/severities/priorities/whatever you call them.
