Review Comment:
I don't think it even make sense to deserialise `extra` because in
Connection (airflow core) this field expected as JSON Object or otherwise it
parse as empty object
https://github.com/apache/airflow/blob/d370362d147ecbbcb699acea3aa33f0be5e24c16/airflow/models/connection.py#L396-L410
Instead of
```json
{
"catalog": "hive",
"protocol": "https",
"session_properties":
"{'hive.insert_existing_partitions_behavior':'OVERWRITE',
'scale_writers':'true','task_writer_count':'1','writer_min_size':'32MB'}"
}
```
user should provide
```json
{
"catalog": "hive",
"protocol": "https",
"session_properties": {
"hive.insert_existing_partitions_behavior": "OVERWRITE",
"scale_writers": true,
"task_writer_count": 1,
"writer_min_size": "32MB"
}
}
```
