Bots in Chrome.LUCI pool are routinely filling up disk

Project Member Reported by jchin...@chromium.org, Sep 18 2017

Issue description

ssh'ing into swarm906-c4 shows most usage is in /b/swarming/w/ir/cache (91G, majority under builder/linux), followed by /b/swarming/c/mC/android/src (34G), /b/swarming/c/EQ/linux/src (70G), /b/swarming/c/I2/android/src (38G), and /b/swarming/c/EH/linux/src (32G).
