Add service name to UPnP mapping descriptions

[ulope]

Is your feature request related to a problem? Please describe.

Depending on the number of installed packages a DAppNode may request a lot of UPnP mappings (in my case currently 21).
The description of every mapping is just DAppNode - that's not very helpful when trying to track down an issue or even just to know why a particular mapping exists.

Describe the solution you'd like

It would be useful, both for debugging and general awareness what's happening in one's network, to include the name of the service that requested the mapping in the description (e.g. DAppNode: Erigon).

Describe alternatives you've considered
