Primary and read replicas

The generated Store is constructed with one primary and one replica. Ordinary reads are balanced across replicas, writes use the primary, and ReadFromPrimary() requests a strong read. Those routing details do not change the generated AccountsReader and AccountsWriter interfaces used by the application.
