Description of problem:
Nagios is not required by default in HCI. So all nrpe related configurations can be removed from generated gdeploy config.
Additional info: bz#1411927 is already raised to get nrpe related information from user and create a correct gdeploy configuration.
Tested with ovirt-cockpit-dashboard-0.10.7-0.0.13
nrpe configurations removed from generated gdeploy config file
