Subject: [PATCH] Additional setup to support native image creation.

 - Switch to Caffeine for caching since it is supported on native unlike Ehcache
 - Use latest metadata repository 0.2.3 (will be the default with Native Build Tools 0.9.15)
 - Registers resource hints for WebJars and db resource directory
