requested to merge lorenz/gitlab-ci-multi-runner:feature/k8s-emptydir into master
Do not update/delete: Banner broadcast message test data
Do not update/delete: Notification broadcast message test data
Adds support for specifying Kuberntes EmptyDirs to the Kuberntes Executor
For running applications that need explicit tmpfs mounts (for example UML which needs a tmpfs without noexec) and for automatic volume cleanup in case a container has declared volume instructions (which would not be cleaned up since they are managed by Docker and not K8s).
I'm not sure if I changed every codepath that deals with volumes
master (if you do - rebase it please)
