LOG_USER is currently hard-coded.  It would be pretty easy to make this 
configurable... LOG_DAEMON may also be a better default choice.

Not currently.  This would be very simple to add.  See mon/LogMonitor.cc:

      if (g_conf->mon_cluster_log_to_syslog) {
	syslog(clog_type_to_syslog_prio(le.type) | LOG_USER, "%s", s.c_str());
      }

We can just add a min log level configurable.

Opened #3704.
