Configuration:

If your nagios cmdfile is not /var/spool/nagios/cmd/nagios.cmd you
can configure ansible (on your nagios server) to use the correct
one by making a file called /etc/ansible/modules/nagios.conf that
looks like this:

[main]
cmdfile = /path/to/your/nagios.cmd

When calling this module via ansible, use the 'cmdfile' parameter to
set it explicitly.
Set the path to the command file explicitly with the 'cmdfile'
parameter.
