Filter cables by connected device

• NetBox version: 2.5.8

Proposed Functionality

Extend the Cable filter set to allow filtering by the connected parent object at either end. For example: /api/dcim/cables/?connected_device=switch42.

Use Case

This would allow an operator to easily return a list of all cables connected to a device.

I have been thinking about suggesting a filter allowing the return of a list of all cables connected at a spesific site, rack, or device - adding two more options to your Use Case description, but I am not sure whether or not this justifies adding two more feature requests or expanding this one?
