Add device description columns to DeviceComponentsTable

Proposed functionality

I would also like to add an additional column for Device Description to all DeviceComponents tables.

And also add an Installed Device Description column to DeviceBay tables.

This does not add any database queries.

Use case

In our environment device descriptions are very important because most devices do not have a hostname. The name field is used only for devices which do have a meaningful hostname. For all the rest, we leave name blank to avoid uniqueness issues.

Here's an example to demonstrate the proposed functionality. We have two Adder ALIF4021T devices, which are mounted side by side in a single RU. To model this in Netbox, I have to model them as children, with a "generic 1U shelf" as the parent. The Device description field is how users tell the difference between the two devices on this shelf.
In this example, the Description column describes the bay itself, which is blank.
Device Description describes the shelf Device.
Installed Device Description describes the Device installed in the bay.

Export templates are the right tool for customizing table output to include additional fields like this. Our view is that this leads to cluttered interfaces and performance issues. Going forward, we're going to be more cautious about accepting new columns that span relationships.
