Ports by device group (#14175)

* Add devicegroup filterFields

* add Devicegroup to post function

* StyleCI

* Add GUI Element

* Less wordy

Dropped "View" from the link. Made it too wordy for such a small GUI insertion.

* Moved DeviceGroup Ports link to a separate column

I realized how it could be confusing to have links to two different items in the same column, so I separated the Ports out.
