Use a Python script to check pertinent details of a Ubiquiti Edgeswitch's configuration

This script prompts for a device IP address, username, and password.
Then it uses the supplied info to SSH to the device, get in to enable mode and then run the command show run.
A backup file named <deviceIP>-backup.txt is created in the same folder as the script.
The script then checks the running config for pertinent details:

• Number of interfaces
• VLANs in VLAN Database
• The Management VLAN
• The number of users as their names
• The switch's Name Server(s)
