note for review.

I decided to not include the container state in the un-marshaler.

1. When a container is un-marshalled, Kura will use the name to query locally for the container and populate its own fields
2. the mapping of the container state, to Kura bundle state is not symmetrical, so we cannot trust the un marshed state
