Scheduler log should report the number of run/skipped/failed test
With now the log looks like:
[2019-10-11 19:34:22,311] Starting 'RUN' 'adb636392b3f -b read.diff'
[2019-10-11 19:46:46,123] Ending 'RUN' 'adb636392b3f -b read.diff'
If we could indicate some data about how that run went, it would be useful to quickly check that all is well.
