Add a way to inspect driver logs during CI

[muzarski]

When running the tests in build folder, the test binary generates a log directory which contains driver (tracing) logs. I often use these during debugging - e.g. to see why the test is failing or what needs to be adjusted.

Sometimes, there may be a test that fails during CI, but we are not able to reproduce it locally. We should add a way to export the log directory with the driver logs during CI.
