Create a Flask app, deployed as a Kubernetes microservice, that creates static HTML version and build dashboards for LSST the Docs products. This service will use LTD Keeper as both a trigger (
DM-9021 will de facto design API endpoints that trigger dashboard builds), and as a data source (use Keeper API to discover editions and builds for a product).
This ticket will establish the basic structure of LTD Dasher. A second ticket will then implement an MVP of the dashboards themselves.
