Jkube: Not able to override Image Name in Simple Dockerfile Mode with `jkube.generator.name`

[rohanKanojia]

When using simple Dockerfile mode, we're not able to override the default image name using jkube.generator.name property. Seems like we always assume image name to be group:artifact:latest in zero dockerfile mode and don't consider whether jkube.generator.name property is set or not, we do pass a defaultImageName but somehow it seems to be passed as null:

In order to reproduce this, you can go to quickstarts/maven/docker-file-simple and try overriding image name by adding some property. I noticed this when testing @ghassen1khalil sample: https://github.com/ghassen1khalil/jkube-error-reproducer
