[keycloak-dev] KEYCLOAK-6990 - Allow agnostic environment configuration in theme

Hello everyone, I started some development on a closed ticket ( https://issues.jboss.org/browse/KEYCLOAK-6990) in order to add the ability to load environment variables through theme.properties for custom themes. I'd need some feedback from you to see if I'm taking the right path here as this is my first Keycloak dev and I'm not an expert in Java nor Maven. This is what I've done so far https://github.com/Opa-/keycloak/commit/8f0517d17bd350d22d082516884a75788... but I'm quite unhappy with the duplication of the maven-surefire-plugin (you can see that on top of my plugin block, there's an existing maven-surefire-plugin plugin block) but I did not found other way to bring an environment variable into the test context. If someone could give me some feedback here it'd be very much appreciated :) Regards, Vincent
