Cluster domain cannot be configured for clean up job

[luischre]

Summary

Currently there is no way to configure the cluster domain for the clean up run. Hence the clean up job fails if it is running within a cluster that doesn't have the cluster domain cluster.local

Could not resolve host: sorry-cypress-2-api.sorry-cypress-2.svc.cluster.local

How to reproduce

Deploy the sorry-cypress charts on a cluster with a different cluster domain.

From what I can see this is due to this line within the cronjob-run-cleaner.yml

- name: sorry_cypress_api_url
  value: "http://{{ include "sorry-cypress-helm.fullname" . }}-api.{{ .Release.Namespace }}.svc.cluster.local:4000"

Instead it should be possible to set the cluster domain as a value:

- name: sorry_cypress_api_url
  value: "http://{{ include "sorry-cypress-helm.fullname" . }}-api.{{ .Release.Namespace }}.svc.{{ .Values.runCleaner.clusterDomain }}:4000"
