Description

There are some required changes already implemented by @ozangunalp. Apart from those, at least the following items are required, adding them here as a checklist to track progress:

• There are some split packages among Apicurio artifacts.
• Each time Vert.x instance is retrieved from CDI there is a message logged on INFO :
  INFO [io.apicurio.registry.client.RegistryClientRequestAdapterFactory] (executor-thread-1) Successfully retrieved a Vertx instance from CDI.
• The image used in Apicurio dev service apicurio/apicurio-registry-mem is no longer maintained in v3. It has to be replaced with apicurio/apicurio-registry
• There are a bunch of class names in the Quarkus processor for native compilation configuration that possibly no longer exist, we need to clean those up
• Verify different auth methods including OAuth working in JVM and Native mode
• Migration guide for config changes etc. + yaml files for quarkus update command
