> The service.MigrationManager class manages a MIGRATION_STAGE where nodes
> should execute db.migration.Migration instances.
> The problem is that the node that a client connects to via Thrift or Avro
> initiates the migration in their client thread (calls migration.apply).
> Instead, the Thrift and Avro clients should ensure that the migration occurs
> in MIGRATION_STAGE, and should block until the migration is applied by the
> stage.
