[powershell]To exclude device from Tufin SecureChange

A real life usage of the device exclusion api.

 Monitoring, on the left panels are a list of your device, focus your mouse
cursor on the panel and type 't' with your keyboard, device id will appear.

This script is just to make exclusion slightly easy, if you do not have powershell ISE, download Postman (https://www.getpostman.com/).
Postman does the same thing as what this script does.
