This updates the Nagios image used to the image that is built
out of openstack-helm-images instead of the image hosted in quay.
This new image includes the updated host definition plugin that
uses the kubernetes python client instead of prometheus queries,
so the check_prometheus_hosts command has also been updated to
reflect the change in required arguments
