Synchronous query first ORM!

In 1.10.0, all query/request to databse is synchronous first! That means NO unnecessary callback composition-decomposition when you call APIs such as model.createSync, instance.saveSync, etc.

• ✨ built-in knex object in DMLDriver, you can get it by orm.driver.knex
• ✨ built-in database-connection-pool, fib-pool function would be called when query executed, enable pool-query by
  • passing pool option when connect database(such as mysql://root:@localhost:3306/schema?pool=true)
  • or setting connection.pool as true
    • ORM.settings.set('connection.pool', true)
    • model.settings.set('connection.pool', true))
• All classical apis compatible 😊
• 🚀 better model & association hooks.
