Prevent chord from printing results to the log

[chaws]

Celery chords is print out the result of all tasks, and it's clogging out worker logs. Ex:

[WARNING] Task tradefed.update_build_status([0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
...157000 zeros later...
, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0], 2840381) consumed 4251MB of memory

Not a high priority though

Hmm, this is actually coming from SQUAD
https://github.com/Linaro/squad/blob/master/squad/celery.py#L35
I'm not sure we can disable it just for this task. Maybe this should be debug not warning?

[chaws]

Humm, I think so.

We will have Sentry notifications anyways if a worker has crossed a certain memory limit

• 1G for regular workers
• 4G for fetch workers

IIRC, that was what Antonio wrote when trying to peek which tasks were consuming the most memory

Indeed, this is how I remember it.
