Description of problem:
Selinux blocks execution of gluster-nagios plugins in the glusterfs node

Steps to Reproduce:
1. In the gluster-nagios server and glusterfs nodes installed setup,
   create a gluster volume and set cluster.server-quorum-type to server
2. bring down one node and check for Cluster-Quorum passive check service
   status information.

Actual results:
Its just displays "OK" in an selinux enabled system.

Expected results:
It should display an appropriate message when all the nodes are down or some nodes or up.

It works for us when we enable the selinux policy using the following selinux policy:

module nsca 1.0;

require {
	type syslogd_t;
	type port_t;
	class tcp_socket name_connect;
}

#============= syslogd_t ==============

#!!!! This avc can be allowed using the boolean 'allow_ypbind'
allow syslogd_t port_t:tcp_socket name_connect;
