Allow running Execution Containers directly on a Kubernetes cluster without a configured worker.

The blog post here describes how to run workers on a Kubernetes cluster: https://octopus.com/blog/kubernetes-workers However, this approach has some challenges because it uses a long-lived container on the cluster to do the work.

It would be great if we could get an option to run ephemeral Execution Containers directly on a Kubernetes cluster without the need of a worker. Or, if instead of having long-lived worker containers on the cluster that directly run tasks, the workers only acted as a "broker", and tasks using that worker launched as new ephemeral containers on the cluster.
