Title: [ARQ-653] Reworked configuration sharing between client and container side.

It's using yaml serialization/deserialization to pass only relevant bits of the persistence extension configuration.

I was having troubles trying to use the same approach on the container side as it's used in ConfigurationRegistrar (Shrinkwrap). Details here: https://gist.github.com/1396309

Pros: compact representation with only relevant stuff for persistence extension.
Cons: different approach, additional dependency for the extension (if you don't want to use YAML for datasets).
