Add ability to specify `host`/`port` for Snowflake connection. At LocalStack, we have recently started building a Snowflake emulator that allows running SF queries entirely on the local machine: https://blog.localstack.cloud/2024-05-22-introducing-localstack-for-snowflake/ . As part of a sample application we're building, we have an Apache Airflow DAG that uses Cosmos (and DBT) to connect to the local Snowflake emulator running on `localhost`. Here is a link to the sample app: localstack-samples/localstack-snowflake-samples#12 Currently, we're hardcoding this integration in the user DAG file itself, [see here](https://github.com/localstack-samples/localstack-snowflake-samples/pull/12/files#diff-559d4f883ad589522b8a9d33f87fe95b0da72ac29b775e98b273a8eb3ede9924R10-R19): ``` ... from cosmos.profiles.snowflake.user_pass import SnowflakeUserPasswordProfileMapping ... SnowflakeUserPasswordProfileMapping.airflow_param_mapping["host"] = "extra.host" SnowflakeUserPasswordProfileMapping.airflow_param_mapping["port"] = "extra.port" ... ```

Add sample app to run DBT transformations via MWAA Airflow. Still needs a few minor fixes in the Snowflake emulator, but mostly already working e2e. 🎉 (Update 2024-06-24: The sample is now working end-to-end with the
latestSnowflake image)Based on this Snowflake quickstart app: https://quickstarts.snowflake.com/guide/data_engineering_with_apache_airflow
