Description
Use buildtool data to generate requested dockerfile buildtool doc command:

Need to add package-fast-jar here: https://github.com/quarkusio/quarkus/blob/master/devtools/platform-descriptor-json/src/main/resources/codestarts/quarkus/core/buildtool/maven/codestart.yml#L29

maybe rename package-uberjar to package-uber-jar

Then use these in the different dockerfiles templates

@glefloch do you receive a notification when assigned?

Yes, I did. I started working on it. This is a good idea. We could also use the buildtool.cli for Gradle project.
