Describe the OAuth method(s) for connecting to Snowflake.

Use this content for the crucial parameters.

BigQuery has an analogous OAuth option & instructions here which can be used for context and inspiration.

Additional information

Snowflake Admins will use instructions like this and this to setup this connection method.

But we want to cover how end users can configuration their connection in their dbt profiles.yml once their admin has set it up.
