How to import Snowflake Database with the Encrypted Extra field

[askldjd]

How to reproduce the bug

In the tutorial, users may use the SECURE EXTRA field to supply a Key Pair as authentication. However, it is not clear how this can be done when the datasources are configured through YAML.

I was able to configure the database manually through the UI. However, when I tried to export the same database, the keypair field does not exist. Looking over the codebase, the import seems to suggest that it should be a field called encrypted_extra.

I tried to supply the encrypted_extra field in the datasource yaml, but the field didn't seem to make it (as indicated by the logs). Any guidance would be greatly appreciated.

Make sure to follow these steps before submitting your issue - thank you!
