For hypervisor-based container runtimes (like Kata Containers, Clear Containers or runv) a pod will be created in a VM and then create containers within the VM. When a runtime is requested for container commands like create and start, both the instal "pause" container and next containers need to be added to the pod namespace (same VM). A runtime does not know if it needs to create/start a VM or if it needs to add a container to an already running VM pod. This patch adds a way to provide this information through container annotations. When starting a container or a sandbox, 2 annotations are added: - type (Container or Sandbox) - sandbox name This allow to a VM based runtime to decide if they need to create a pod VM or container within the VM pod.
