Replace / complement streamlit with Lightdash

[dcaribou]

Lightdash is an open source BI solution that runs on top of dbt's Semantic Layer. It would be interested to be able to ship a few dashboards within the project, and Lightdash can be helpful for that.

Currentlly Lightdash support only a few enterprise adapters (BQ, RS, SF...). DuckDB is not supported. I've explored https://github.com/jwills/buenavista as a potential workaround, but it does not seem easy to integrate.
