Title:
  nrpe checks are partially ignored by nagios

Status in Nagios Charm:
  New
Status in NRPE Charm:
  New

Bug description:
  In a kubernetes model, we have some kubernetes-worker charms
  (kubernetes-worker-gpu) with a relation to an nrpe charm (nrpe-
  kubernetes-worker-gpu). The nrpe charm has a relation to a nagios
  charm (nagios-server-k8s).

  If we list the nrpe-checks it looks like we have a few:

  $ $ juju run-action --wait nrpe-kubernetes-worker/8 list-nrpe-checks
  unit-nrpe-kubernetes-worker-8:
    id: 37d06ff4-6861-496f-8a2e-cd3464991782
    results:
      checks:
        check-arp-cache: /usr/local/lib/nagios/plugins/check_arp_cache.py -w 60 -c 80
        check-conntrack: /usr/local/lib/nagios/plugins/check_conntrack.sh -w 80 -c 90
        check-disk-root: '/usr/lib/nagios/plugins/check_disk -u GB -w 25% -c 20% -K
          5% -p / '
        check-docker: /usr/local/lib/nagios/plugins/check_systemd.py docker
        check-flannel: /usr/local/lib/nagios/plugins/check_systemd.py flannel
        check-load: /usr/lib/nagios/plugins/check_load -w 192,96,48 -c 384,192,96
        check-mem: /usr/local/lib/nagios/plugins/check_mem.pl -C -h -u -w 85 -c 90
        check-snap:
          kube-proxy:
            daemon: /usr/local/lib/nagios/plugins/check_systemd.py snap.kube-proxy.daemon
          kubelet:
            daemon: /usr/local/lib/nagios/plugins/check_systemd.py snap.kubelet.daemon

  But we don't find all of them in nagios (check-snap checks are
  missing):

  $ juju run --unit nagios-server-k8s/6 -- grep -r "service.*kubernetes-worker-gpu" /etc/nagios3/conf.d/
