CI stdout is printed to file instead of console (d2iq-archive#5633)

Summary:

We're printing CI logs (sbt test integration:test...) directly to a log file. This should:
- improve CI run time since we don't print to console and upload zipped artifacts (1/10 of log size)
- theoretically solve our "jenkins log loop" problem by printing only very few lines (`stderr`) to console
- logs are archived by Jenkins
Additionally an old remnant (`review.py`) of phabricator times was removed.
