Collect iptables rules needed for all existing syslog exporters and verify
if the existing iptables rules are the same. If not, remove the stale rules
and add the new rules to make sure all exporters work properly.
Adds a rule for exporting syslog information to a specified server. The
required parameters are the rule name (exporter_name); severity level
(emerg, alert, crit, and so on); transmission protocol (TCP or UDP); and
server IP address or hostname. The optional parameters are the syslog port
number, which can be 1 through 65,535 (514, by default); facility level to
use when logging messages to syslog (kern, user, mail, and so on); and
message IDs (msgids), which identify the types of messages to export.
