dag_run table - replace column conf type - byte ( that store a python pickle ) by a JSON

[raphaelauv]

Description

the column conf of the table dag_run is using the type byte ( and storing a python pickle ) on the database , since airflow only support postgres 12+ and mysql 8+ , we could use a json type .

And also the user could search "efficiently" in the web-ui a dag_run based on the parameters thanks to that change
