Create subclasses of EntityManagerException for certain DatastoreExceptions.

Use the code from DatastoreException to throw a subclass EntityManagerException. Some useful exceptions would -

EntityAlreadyExistsException - if an attempt was made to insert a duplicate key EntityNotFoundException - if an attempt was made to update a nonexistent entity
