Underpass production deployment #386
Description
Architecture:
Underpass
This is the data engine, which download and processes OSM data, storing the results into the Underpass PostgreSQL DB. It's a C++ program, compiled as a binary. It can be installed in a container. There's a bootstrap manual process that's needed before running the program that will keep the database updated minutely.
Underpass DB
Currently, the same database is storing both Raw Data (ways polygons, ways lines and nodes) and Underpass data (changesets, validation). This database will store data for 4 countries at first (one per HOT Hub).
Underpass API
Based on Fast API, it can be deployed in a container. It needs connection to the Underpass DB. It will receive requests from the Underpass UI components used into the HOT's Tasking Manager.

yarn add https://github.com/hotosm/underpass-ui.git
It was implemented into the TM already. There's a PR waiting for review:
