Run dind container as a Sidecar

Currently, in dind mode we run 2 containers in the pod. This results in them having their own lifecycles. In the case of dind this could lead to issues as the process in the runner container depend on the docker socket from the dind container. We hit that multiple times were we wanted to wait for jobs to complete and the runner container stays alive as we handle the SIGTERM manually but dind dies and the jo fails. When running as a Sidecar container dind stays alive as long as the pod is alive and we don't need to do custom SIGTERM handling there.

Since 1.29 Sidecars are enabled by default so this PR moves the dind container as a Sidecar if the version is above 1.29.
