feat: templating support in appliciation property files #27
Description
For more advanced shenanigans in application properties, we could consider running it through helm tpl function.
Consider
- always template, if profile properties are provided as value as a string, not as a map
- introduce a dedicated valuesTemplate type that always expects a template string
Probably prefer the later option. Could be annoying if a user needs to configure a template for there application and helm preprocesses it.
