test: use remote coverage

[lukasmetzner]

We have already implemented this in the csi-driver. With this solution we can test more paths (e.g., metrics) in the code and get a more accurate test coverage.

we can test more paths (e.g., Robot)

Do you plan to add this in a follow-up PR?

Actually, I have made a mistake here. It should be (e.g., Metrics), as we do not upload the Robot coverage. I will correct the PR description.

Tackling the Robot coverage would be nice though.
