Versions in chart and values.yaml

In general it should not be necessary to specify any version like image tags in the values particularly for production deploys. These tasks are identified so far:

• Deployments like for the cache use already {{ .Values.cache.image.tag | default ( print "release-" .Chart.AppVersion ) }}. Confirm that the fallback to AppVersion is actually working for all deployment.
• The tag version in values.yaml should not be needed anymore and probably be removed.
• helm template without providing any values should run successfully.
• Remove versions in flux helm releases
