[RFE] if syslog-ng is main syslog, validate its syntax about supportutils HOT 5 CLOSED

man rsyslogd | col -b | sed -nr '/^[[:blank:]]+\-N +level/,/^$/p' | fmt -w 80
       -N  level
              Do a config check. Do NOT run in regular mode, just check
              configuration file correctness.  This option is meant to verify a
              config file. To do so, run rsyslogd interactively in foreground,
              specifying  -f  <config-file> and -N level.  The level
              argument modifies behaviour. Currently, 0 is the same as not
              specifying the -N option at all (so this makes limited sense)
              and 1 actually activates the code. Later, higher levels will
              mean more verbosity (this is a forward-compatibility option).

rsyslogd -N 1 -f /etc/rsyslog.d/remote.conf
rsyslogd: version 8.39.0, config validation run (level 1), master config /etc/rsyslog.d/remote.conf
rsyslogd: there are no active actions configured. Inputs would run, but no output whatsoever were created. [v8.39.0 try http://www.rsyslog.com/e/2103 ]
rsyslogd: run failed with error -2103 (see rsyslog.h or try http://www.rsyslog.com/e/2103 to learn what that number means)

Added system logging configuration and checking in messages_config.txt issue#103
