    Fix shared-pools lbaas_listeners migration

    This patch fixes the MySQL-specific features in the alembic
    migration for shared-pools, so that migrations can also work
    on PostgreSQL.

    This patch also removes the uniqueness of the SQLAlchemy model
    definition of the Listener.default_pool_id field. (This was
    mistakenly left in place in the shared-pools patch.)
