When adding some feature packs on top of existing installation, the provisioning configuration might need to be changed.

For instance when installing org.wildfy:wildfly-galleon-pack on top of server provisioned from org.wildfly:wildfly-ee-galleon-pack, the resulting provisioning configuration should replace the org.wildfy:wildfly-galleon-pack configuration with the new feature pack rather than listing both feature packs.

It should also be possible to install additional packages when adding feature packs.

The proposal is to add a feature-pack-templates.yaml configuration file with following schema:
{{}}
schemaVersion: 1.0.0
feature-packs:
  - groupId: "org.groupId"
    artifactId: "artifactId"
    version: "[0,)"
    supports-customization: false
    requires-layers: false
    replaces-dependency: "org.groupId:artifactId"
   additional-packages:
    - example.package
