- Avoid having to pass the khoj_sample.yml data file into pip, native apps
- Packaging data files into python packages is annoying.
- There's `MANIFEST.in`, `data_files` and `package_data` in setup.py
- Bdist, wheel, generated source tarball use different set of these fields
and put the data files in different locations
- Rather just code the default config into a constant. Avoid
pointless file reads as well this way
- Include khoj_sample.yml in pip package to load default config from
- Create khoj config directory if it doesn't exist
- Load config from khoj_sample.yml if khoj.yml config doesn't exist
- Reduce size of app copied to container by adding unneeded
directories to .dockerignore. E.g Ignore docs, tests, pip build, dist
- Update MANIFEST.ini to include web, emacs interface directories
Web directory is used by the web interface which will be exposed by
the docker container
