Detect and automatically map the system properties that are used in the application.properties

[Sgitario]

For example, if we add the following configuration:

quarkus.datasource.jdbc.url=${POSTGRESQL_URL}
quarkus.datasource.username=${POSTGRESQL_USERNAME}
quarkus.datasource.password=${POSTGRESQL_PASSWORD}

I would like that the Quarkus HELM extension to automatically map those values into the generated Values.yaml file as:

app:
  envs:
    POSTGRESQL_URL: 
    POSTGRESQL_USERNAME: 
    POSTGRESQL_PASSWORD: 

At the moment, the only workaround is to configure either Kubernetes or Openshift as follows:

quarkus.openshift.env.vars.POSTGRESQL_URL=jdbc:postgresql://host:1111/database
quarkus.openshift.env.vars.POSTGRESQL_USERNAME=user
quarkus.openshift.env.vars.POSTGRESQL_PASSWORD=pass

And now, the Quarkus Helm will map those values.

It would be great if we could automatically find the system properties without needing to configure quarkus.openshift.env.vars.xxx.
