Research: Automation of Helm Chart releases and maintenance

[mowies]

This ticket shall be used to track research for #394.

Generally, the plan is to have a separate place for the helm chart and then have separate releases and version numbers that get released automatically through the chart-releaser-action.

Important questions and unknowns that shall be researched:

• can we fully generate a helm chart through kustomize?
• should we combine kustomize with helm or can we maybe replace kustomize with helm?
  • if we combine kustomize with helm, how would that affect the future maintainablilty of the project?
• how would the process look like when a user requests a feature for the helm chart, e.g. a new helm value?
• should we maintain 2 types of how to install the KLT? (manifests/helm)
• if we decide to use helm, should we keep the charts in the same project, or create a separate project for the helm charts and maintain them there?
