Input VSPHERE : Distributed Port Group

### Use Case

we need that the distributed port group to be the name of the network interface.

Actually, it seem that only vswitch standart is operationnal

### Expected behavior

We want only interface=tn-run2|ap-intranet-ppd-t5_|epg-global.
We want only network card connected.


### Actual behavior

Actually, we have interface="vmnic0", interface="vmnic1"

### Additional info

_No response_

The issue does not name a file, test, or entry point. Start by locating Telegraf’s vSphere input implementation and its existing tests, then reproduce the distributed port-group case; done means the interface uses the distributed port-group name and only the expected connected network card is reported.
