Visualize cost information in Coda

Once we have created useful data views for our cost information (#430, #247), let's experiment with visualizing them in Coda. This would require creating a new service account for Coda and learning how to use its Snowflake pack.

Note that there are some steps in Snowflake that require ACCOUNTADMIN role to complete, specifically to enable OAuth security integration.

Also on the Coda side this will require a Coda admin so we will need to loop in ODI IT once we have the Snowflake prerequisites in place.
