HSHARDS-9
Added ShardAware interface.
We use interceptors to set the shard on the entity when the entity is saved or loaded.
Reworked how we deal with interceptors as part of this CL.
Deleted: shards/trunk/src/java/org/hibernate/shards/session/CrossShardRelationshipDetectingInterceptorDecorator.java
