Use Version#getId() instead of Version#getName()
Minor fixes
[FABRIC-429] Better handling of container metadata
Add the ability to specify the version and profiles to use at container creation time instead of setting those just after
[FABRIC-429] Change the agent to use the FabricService instead of using zookeeper directly
Add a getOverlayProfile() method on the Container to easily have a global view of the configuration for a given container
[FABRIC-429] Change the ConfigAdmin / Fabric bridge to not depend on zookeeper and put the heavy work inside the fabric service / data store
Fix some unit tests
