To add a configuration test for authetication.sh script

[sansyrox]

Describe the bug
Right now when the script authentication.py is called, it only stores the email credentials in the JSON file without even checking the authenticity (assuming correct details are supplied from the mobile clients) and not updating details on the server.

Expected behavior
To create a systemd file which executes after an internet connection has been established and then execute authentication.py script

Would you like to work on it?
