Cable trace api not found for front-ports and rear-ports

[4nqyi]

I can reach the UI trace page but not the api for rear-ports and front-ports.
Searching shows that this was fixed: #4736
We're running v3.2.5.

Looking at the self-hosted REST API documentation in 3.2.8 there are .../trace/ endpoints for console-ports, console-server-ports, interfaces, power-feeds, power-outlets, power-ports; but not for front-ports or rear-ports.

I guess this is a regression since #4736.

• 16cdf30 (linked from that issue) introduced test_trace_frontport and test_trace_rearport test cases
• 5ed6136 moved them into ComponentTraceMixin
• df73737 ("Remove legacy connection_status fields") removed Mixins.ComponentTraceMixin from FrontPortTest and RearPortTest

So from that point onwards, there was no test case coverage for this feature.
