allow configuring dataset model uri collation

[zhangyangyu]

Description

Currently, the dataset model's uri column has a hard code collation. The 'latin1_general_cs' collation is not supported by some MySQL compatible database, like TiDB. So it's not possible to use the database with Airflow while most other features are compatible.

airflow/airflow/models/dataset.py

Line 59 in 17e5e7b

collation="latin1_general_cs",

Use case/motivation

Allow users to customize the collation while still default to 'latin1_general_cs'.

@zhangyangyu Adding a new Airflow configuration to configure the table collation and set its default value to latin1_general_cs can do the job, I assigned you.
