quarkus-container-image-jib should support jib.dockerClient.executable config

[snowdrop-bot]

Jib allows configuration of the dockerClient that is invoked for loading the built image to local registry. This allows developers to explicitly build to docker, podman, buildah, etc. depending on what is available on their system as well as explicitly selecting one of them if multiple are present. This is analogous to the quarkus.docker.executable-name config property that is already supported, so I think it would make sense that the jib builder supports it as well.

There is also the dockerClient.executable config property that Jib supports which I think might be relevant here. If it is not then I think that a separate issue could be opened to add support for this to the quarkus-container-image-jib build plugin as quarkus.jib.dockerClient.executable=/usr/bin/podman. I use this in Cryostat to default the image builder to podman, but allow it to be overridden if some developer needs that to be docker (or probably buildah too - haven't tried that yet).
