@jaketf I'd love to do it.

Small update:
I tried to complete this ticket but couldn't test Airflow with Kerberos because the Kerberos setup in Breeze is not complete.
I have a new setup: https://github.com/mik-laj/presto-kerberos-docker

I also opened PR to presto-python-client to add support for self-signed SSL certificate: trinodb/trino-python-client#36
I will have to prepare some documents so that this change can be merged, but that doesn't block us as I have a workaround.

Small update:
I have a working PR, but it still needs some care to make everything easily accessible with the breeze command.

One problem has already been found thanks to system tests. Snowflake-connector-python library monkey patch Python core. It enforce SSL certificates verification ,so it cannot be turned off certificate verification for developing purposes. We will probably have to report the bug to the maintainers of this library, and for now I will have to skip tests for Salesforce.
