feat(api): add Athena workgroups and a query editor to the cloud explorer

Create and delete Athena workgroups (with a result folder, optionally
enforced), and run SQL in one: pick a database from the Glue Data Catalog,
preview a table, run with Ctrl+Enter, cancel a running query, read up to 1,000
rows and download the full result CSV from S3. Recent queries in the workgroup
can be reopened. TheCloud runs the SQL for real over the files a Glue table
points at. The Glue page links to the editor.
