> Introduce *initialize* and *destroy* container API into the
> *ContainerManagementProtocol* to 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*
