PersistentEntity to glue together Sharding and PersistentBehavior better

Browse source 
* Makes the combination more visable
* You don't have to worry about the persistenceId, only EntityTypeKey and entityId
* The glue is stronger in the javadsl because of two reasons
  * Couldn't realisticly create a PersistentEntity class extending PersistenBehavior (which
    contains all the optional parameters and functions) since that would duplicate too much.
  * The ActorContext would be needed in the ShardedEntityContext parameter and because of the
    additional M type parameters the type inference breaks down when using the factory. Would
    require specifying the type of the ShardedEntityContex[M] parameter. That problem doesn't
    seem to exist in Java.
