[docker] use `--no-cache-dir` flag to `pip` in dockerfiles to save space
using "--no-cache-dir" flag in pip install ,make sure downloaded
packages by pip don't cached on system . This is a best practice
which make sure to fetch from repo instead of using local cached one .
Further , in case of Docker Containers , by restricting caching ,
we can reduce image size.
In term 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 reduce a lot by don't caching pip packages.
Further , more detail information can be found at
