This restarting test start with 7.1 version and setup the sample rate for transaction log, then it test with 7.3 version and verify transaction log are still being written.

This test use latency as the sample transaction log metric.

Now only code is added, but it is not run by simulation. It will be run as part of the restarting test in simulation in 7.3
