This is a revert of 1da5a removing actual deployments and keeping
only the dev environment in Tilt.
The clean-up was a bit heavy handed. We should keep the Helm
chart to the development repository and move away only the
deployment configuration.
The ingress was the same for the frontend, the
backend and the websocket, but the websocket
needs to be handled differently, so we created
a new ingress specifically for the websocket.
