URL: https://github.com/apache/airflow/pull/19733


   Hi, I was using the Trino provider package of airflow. While using I found 
out that I am not able to set `session_properties` for the Trino connector.  So 
I am creating this PR to fix this. This way if the user needs to add 
session_properties from Airflow UI they can add it like below
   
   ```
   {"catalog": "hive", "protocol": "https", "session_properties": 
"{'hive.insert_existing_partitions_behavior':'OVERWRITE', 
'scale_writers':'true','task_writer_count':'1','writer_min_size':'32MB'}"}
   ```
