using --no-cache-dir flag in pip install, make sure downloaded packages
by pip don't cache on the system. This is a best practice that makes sure
to fetch from repo instead of using local cached one. Further, in the case
of Docker Containers, by restricting caching, we can reduce image size.
In terms of stats, it depends upon the number of python packages
multiplied by their respective size. e.g for heavy packages with a lot
of dependencies it reduces a lot by don't cache pip packages.
