[BDGR-177] Run "standalone" tests against live Server

[markspolakovs]

I know that the purpose of "standalone" tests was to speed up Desktop test runs. But I wonder if we could also run them against a live Server.

The biggest difficulty will likely be setup - we'll need to set up a Server environment that matches the respective scenario. We could start out by only supporting tests that use default and having bespoke setup code for that. Alternatively we do some sorcery to import a setup function from the conformance test.
