exec plugin: Removed the Nagios logic from the plugin.

Instead point users to the `exec-nagios.px' script in collectd-exec(5).

-The executable is treated as a Nagios plugin. That means that the first line
-printed to C<STDOUT> by this program is used as the text of a notification and
-the severity of the notification depends on the exit status of the executable
-only.

-For information on how to write Nagios plugins please refer to the Nagios

-complain on the collectd mailing list instead.

+=head1 USING NAGIOS PLUGINS
+
+Though the interface is far from perfect, there are tons of plugins for Nagios.
+You can use these plugins with collectd by using a simple transition layer,
+C<exec-nagios.px>, which is shipped with the collectd distribution in the
+C<contrib/> directory. It is a simple Perl script that comes with embedded
+documentation. To see it, run the following command:
+
+  perldoc exec-nagios.px
+
+This script expects a configuration file, C<exec-nagios.conf>. You can find an
+example in the C<contrib/> directory, too.
+
+Even a simple mechanism to submit "performance data" to collectd is
+implemented. If you need a more sophisticated setup, please rewrite the plugin
+to make use of collectd's more powerful interface.
