feat: template configmaps

[jagregory]

The Kratos chart allows templating the config settings in the chart values via the Helm tpl function, but the other charts don't allow this. Templating is very helpful for if you need to provide values which are based on other values in your environment, e.g. if parts of URLs include the {{ .Release.Name }} as they do with many 3rd party charts.

This PR includes:

• Keto: add tpl to the existing keto.configmap helper
• Hydra: add tpl to the existing hydra.configmap helper
• Oathkeeper: add a oathkeeper.configmap helper which behaves the same as the other charts

As with the second PR, nothing against, just please update the hacks/values to include such an example in tests (mostly static validation, to ensure the output yaml is stil valid) :)
