Kubetools

- Update kubernetes api create job with non-blocking option

- Translate k8s-style `command`/`args` options to docker[-compose]-style `entrypoint`/`command`

This is breaking backwards compatibility for any project using `entrypoint`/`command` options in a `dev` section.
These need to be renamed resp. `command`/`args` to be picked up. The bright side of this is that these cases
will now only require 1 copy of the options when the same values were just repeated under `dev` to get them to
work with `ktd` (`docker-compose`)

- Ignore pods with no owner metadata when restarting a service

- Fix call to check if service exists

- Remove Kubernetes jobs after they complete successfully

- Allow to run upgrades and tests on any container using a containerContext. Especially allows containers that use a released image rather than a Dockerfile
