> 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*
