Previously, only Windows had the plumbing to rename test results for
the Kokoro result viewers to pretty-print.
macos.cfg was the only CI that lacked a corresponding .sh, which maked
unix.sh harder to reason about. Created macos.sh so that unix.sh is now
just a helper script and will not be called directly by Kokoro.
We now avoid "gradle clean" to avoid wiping results. Still clean compiler
since we do re-run the build multiple times with varying platforms.
Shouldn't be necessary, but "just in case" since I want this commit to
be low risk. This improves Windows to produce detailed results even
if the CI was successful.
We've had a long run of test timeout failures on Mac with timeouts in
the seconds. Multiple of these haven't seemed like races, but simply
that the Mac machines were too slow. The most recent case for this is a
set of timeouts for
OkHttpTransportTest.earlyServerClose_serverFailure_withClientCancelOnListenerClosed
where it took over a second for a server stream to be created ("Timed
out waiting for server stream").
This commit reduces the number of workers to reduce the overall load,
hoping this lets tests complete within a reasonable amount of time.
