REF: https://bugzilla.tianocore.org/show_bug.cgi?id=4580
This BZ has been created to provide the sample python scripts to demonstrate
the socket client capabilities using http library on UEFI shell with the help
of Python UEFI interpreter.
The http_echo_client.py and http_echo_server.py scripts are provided as sample
scripts to exercise the python http library from UEFI shell.
