Move container exit state to after cleanup.

Browse source 
Before this change, there is no way to know if container (runtime)
resources have been cleaned up unless you actually remove the container.

This change allows callers of the wait API or the events API to know
that all runtime resources for the container are released (e.g. IP
addresses).
