Summary: chromium.perf/Android Nexus Perf triggers tasks with unsupported dimensions (was: bot affinity 'build199-b7--device1', 'build199-b7--device2', 'build199-b7--device3', 'build199-b7--device4', 'build199-b7--device5', 'build199-b7--device6', 'build199-b7--device7', 'build200-b7--device1', 'build200-b7--device2', 'build200-b7--device3', 'build200-b7--device4', 'build200-b7--device5', 'build200-b7--device6', 'build200-b7--device7', 'build201-b7--device1', 'build201-b7--device2', 'build201-b7--device3', 'build201-b7--device4', 'build201-b7--device5', 'build201-b7--device6', 'build201-b7--device7' is broken on chromium.perf/Android Nexus5 Perf, affecting 159 tests)
The issue seems to be that the builder triggers swarming tasks that have no bots:

https://ci.chromium.org/buildbot/chromium.perf/Android%20Nexus5%20Perf/1792

Sample task: https://chrome-swarming.appspot.com/task?id=3dc8bb6157656310

The offending dimension is device_os: KOT49H0 (there is only device_os: KOT49H).

+jbudorick, bpastene: FYI, in case you know what might've happened.

Comment 2 by sergeybe...@chromium.org, May 30 2018 

The last build that didn't exhibit this error didn't specify device_os: https://ci.chromium.org/buildbot/chromium.perf/Android%20Nexus5%20Perf/1790

Sample task: https://chrome-swarming.appspot.com/task?id=3dc5568312ca1b10

Comment 3 by jbudorick@chromium.org, May 30 2018 

a 7 character build ID seems like a typo in https://chromium-review.googlesource.com/c/chromium/src/+/1076670

Comment 4 by sergeybe...@chromium.org, May 30 2018 

Last "good" build started on 2018-05-29 8:18 AM (PDT)
First "bad" build started on 2018-05-29 1:51 PM (PDT)

Something must have changed in between.
