Summary: The `TransactionalTelemetryTest`s are flaky because they use a real clock and assert on how much time has passed (with a threshold, but that's no good either). Using the real clock in the test is the cause for the test to be flaky because it depends on the assumption that it's the sole process running, never risking to be put in the process-queue of the OS. However, that's not the case and is why the test sporadically fails if the OS decided to schedule other threads/process in the middle of the test. This diff allows parametrising the `TransactionTelemetry` class with the clock implementation so that tests can use a Mock Clock if desired (separate diff).
