    Description

      Introduce initialize and destroy container API into the ContainerManagementProtocol and decouple the actual start of a container from the initialization. This will allow AMs to re-start a container without having to lose the allocation.

      Additionally, if the localization of the container is associated to the initialize (and the cleanup with the destroy), This can also be used by applications to upgrade a Container by re-initializing with a new ContainerLaunchContext
