Assume port 20408 for GRPC exporter

[aparcar]

We assume port 20408 already for coordinator and client, however not for the exporter. I suggest we check if the line mentioned below checks for a port, and if it does not exists, add port 20408.

labgrid/labgrid/remote/exporter.py

Line 1028 in ae09079

"coordinator": args.coordinator,

We do, we either get the env variable LG_COORDINATOR or fallback to 127.0.0.1:20408:

labgrid/labgrid/remote/exporter.py

Line 989 in ae09079

default=os.environ.get("LG_COORDINATOR", "127.0.0.1:20408"),

Ah, only the port argument is inconsistent. I guess @Bastian-Krause fixed this for the client since the client requires the proxy-manager to work, I am not against a fix for the exporter.

I guess this doesn't have a priority, it's just a inconsistency in the setup.
