optimize size and time using "--no-cache-dir"
Using "--no-cache-dir" flag in pip install ,make sure dowloaded packages
by pip don't cached on system . This is a best practise which make sure
to fetch ftom repo instead of using local cached one . Further , in case
of Docker Containers , by restricing 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

Passwords should be hashed using Bcrypt :
```
-# pip3 install bcrypt # if you don't have the bcrypt python lib installed, should be done once.
+# pip3 install --no-cache-dir bcrypt # if you don't have the bcrypt python lib installed, should be done once.
# python3 -c 'import bcrypt; print(bcrypt.hashpw("password".encode(), bcrypt.gensalt(rounds=10, prefix=b"2a")))'
