Add nrpe3, Nagios Remote Program Execution ver 3.

Add nrpe3, version 3.2.0.  NRPE is used to execute remote commands on
machines to monitor them with nagios, icinga or similar programs.

This is added as a separate port, since there are some backwards
compatibility issues with nrpe ver 2.

Update conflicts for nrpe.

+nrpe is used to execute Nagios plugins on remote hosts and report the results
+to the main Nagios server. From the Nagios homepage:
+
+Allows you to execute "local" plugins (like check_disk, check_procs, etc.) on
+remote hosts. The check_nrpe plugin is called from Nagios and actually makes
+the plugin requests to the remote host. Requires that nrpe be running on the
+remote host (either as a standalone daemon or as a service under inetd).
