Disabling it entirely until webrtc:6057 is fixed. > > BUG=webrtc:6057 > > Committed: https://crrev.com/bb66ec35739830847bfb0146cd029ca41421b2d8 > Cr-Commit-Position: refs/heads/master@{#15594} TBR=marpan@webrtc.org,sprang@webrtc.org,skvlad@webrtc.org # Not skipping CQ checks because original CL landed more than 1 days ago.
