[keycloak-dev] Support for themes in the new deployer

Hi, The new provider deployer is incredibly cool! But could this approach be extended to themes, so that they'd be deployed from the same archive? As of 2.5.0, the preferred way to deploy providers is via the "deployments" directory. But let's imagine a complete Keycloak extension that comprises several providers and a GUI theme. ATM, there are three deployment options: - old school: package everything into a JAR and deploy it as a module; - package providers and themes separately, deploy the former via the new mechanism and the latter as a module; - package everything into a single JAR and deploy via the new mechanism. This dynamically deployed module, according to JBoss/WildFly conventions, will be named "deployment.my-module-XYZ.jar"; use this name in the main config to load theme from the module. This is hacky and requires restart, which renders unusable the whole idea of hot (re)deployment. However, there could be another option, more natural and simple one, that is to automatically deploy providers *and* themes from the same archive placed into the "deployments" directory. What do you think? Cheers, Dmitry
