This will allow troubleshooting by getting the actual khoj version
being used. Previously it was always set to a static 0.0.0 version
Command to build Khoj docker image with dynamically set current app version:
`docker-compose build server --build-arg VERSION=$(pipx run hatch version)'
- Our pypi package currently does not work because the django app and associated database is not included. To remedy this issue, move the app into the src/khoj folder. This has the added benefit of improved organization of the codebase, as all server related code is now in a single folder
- Update associated file paths and system references
- Add a productionized setup for the Khoj server using `gunicorn` with multiple workers for handling requests
- Add a new Dockerfile meant for production config at `ghcr.io/khoj-ai/khoj:prod`; the existing Docker config should remain the same
