Upload E2E logs upon failure

[chatton]

Summary

We should upload all container logs upon test failures for easier debugging.

I haven't looked too much into it yet, but I believe we will need to write logs to disk before teardown (as all the containers get removed). After the test is finished running, we can use a follow up step to upload logs only upon test failure.
