----------------------------------------

Forgot to add - still need to add tests for the container state transitions.

> Depending on when ContainersLaunch starts a container, {{KILL_CONTAINER}} when container
state is {{LOCALIZED}} ({{LAUNCH_CONTAINER}} event already sent) can end up generating a {{CONTAINER_LAUNCHED}}
event - which isn't handled by ContainerState: {{KILLING}}. Also, the launched container won't
be killed since {{CLEANUP_CONTAINER}} would have already been processed.
