TASK 13 - Linux User Expiry
REQUIREMENT:
A developer John has been assigned Nautilus project temporarily as a backup resource. As a temporary resource for this project, we need a temporary user for John. It’s a good idea to create a user with a set expiration date so that the user will not be able to access servers beyond that point.
Therefore, create a user named john on the App Server 1. Set expiry date to 2021-12-07 in Stratos Datacenter. Make sure the user is created as per standard and is in lowercase.

#1) Respect the privacy of others.
#2) Think before you type.
#3) With great power comes great responsibility.
