Allow comments in device type import model

[jmanteau]

Environment

• Python version: 3.6.9
• NetBox version: 2.7.7

Proposed Functionality

Currently device type import does not propose comments to the import. (Original PR #451). This feature request is to propose adding the support of comments to the device type import model.

Use Case

This would allow to add information regarding a model such as:

• WS-C2960-48TC-L: Catalyst 2960 - 48 100M data-only copper ports with dual-purpose ports (10/100/1000 or SFP) uplinks - LAN Base
• add the URL to the vendor website.
• etc

This could be interesting when coupled with https://github.com/netbox-community/devicetype-library

This was considered and declined during implementation of the import function. Comments are not included because they are not part of the real-world device definition.
