nagios-server-addons: Fix for dummy config file issue.

This patch replaces the configfile node1.cfg(gluster-host)
by temp_node1.cfg which is of type linux-server having
service PING. And this dummy config file is renamed to
temp_node1.cfg.sample during auto-discovery as it is not
needed after we configure actual hosts. Also this patch
sets the config variable allow_empty_hostgroup_assignment
to 1, which is needed for nagios to allow declaration of
empty host-group with services.
