NetworkErrorLoggingEndToEndTest flaky on win10_chromium_x64_rel_ng

Project Member Reported by kbr@chromium.org, Apr 6 2018 
Following on to Issue 820950, multiple tests in NetworkErrorLoggingEndToEndTest (net_unittests) are flaky on the win10_chromium_x64_rel_ng tryserver. This is causing valid CLs to be rejected from the CQ.

Examples:

NetworkErrorLoggingEndToEndTest.ReportNetworkError
https://ci.chromium.org/buildbot/tryserver.chromium.win/win10_chromium_x64_rel_ng/117869
https://chromium-swarm.appspot.com/task?id=3cb0e9f9e9e19c10&refresh=10&show_raw=1

NetworkErrorLoggingEndToEndTest.UploadAtShutdown
https://ci.chromium.org/buildbot/tryserver.chromium.win/win10_chromium_x64_rel_ng/116947
https://chromium-swarm.appspot.com/task?id=3cac215b24ec3810&refresh=10&show_raw=1

Both tests timed out, including during all of the retries.

This https://chromium-review.googlesource.com/c/chromium/src/+/996093 may help. If not, we can disable it again.

I'm still hitting these flaky hangs on CQ this morning (and I can repro easily locally on Windows with out\Release\net_unittests.exe --gtest_repeat=10 --gtest_filter=NetworkErrorLoggingEndToEndTest*)

Comment 3 by gab@chromium.org, Apr 11 2018 

FWIW, I added a few base::debug::StackTrace().Print(); in the test to see what happens when the test doesn't hang (hinting at what doesn't happen when it does hang) :

Test passes (no hang) :

Comment 6 by juliatut...@chromium.org, Apr 11 2018 

I'm working on a CL here that I can run past the trybots to debug this, but a couple of LOGs or stack traces in net/reporting/reporting_uploader.cc could help -- I'm not actually sure whether we're ever starting the request we expect.

Disable flaky NetworkErrorLoggingEndToEndTests under OS_FUCHSIA.

These tests are already disabled under OS_WIN, so just add OS_FUCHSIA to
the preprocessor condition.
