Subject: [PATCH] Add Kerberos support to Presto JDBC Driver (#16307)
* Add Kerberos support to Presto JDBC Driver
Adding Kerberos properties as DB details properties
Refactoring utility methods for dealing with additional options
Adding test for Kerb properties -> connection string
Adding GitHub action to run integration test
Start to move logic for capturing necessary files to new script, and calling that from mba run
Adjust settings in `metabase.test.data.presto-jdbc` to capture test parameters
