[openshift-support] runAsUser=1000 preventing from running pods

[raffaelespazzoli]

In OpenShift the uid of non privileged pod is randomized. the k8gb chart tries to set runAsUser to 1000 preventing the k8gb and the externalDNS pods to start. I don't see a reason why for these pods a specific uid this would be needed.
Possible solutions:

1. let the user specify the uid, guid via chart parameter
2. automatically set an acceptable value using the lookop function. The look up should do the equivalent of the following:

  export uid=$(oc get project k8gb -o jsonpath='{.metadata.annotations.openshift\.io/sa\.scc\.uid-range}'|sed 's/\/.*//')
  export guid=$(oc get project k8gb -o jsonpath='{.metadata.annotations.openshift\.io/sa\.scc\.supplemental-groups}'|sed 's/\/.*//')

3. for OpenShift don't set any value.
