No LGTM from a valid reviewer yet. Only full committers are accepted.
Even if an LGTM may have been provided, it was from a non-committer or
a provisional committer, _not_ a full super star committer.

Note that this has nothing to do with OWNERS files.

A revert of this CL (patchset #1 id:1) has been created in
https://codereview.chromium.org/662963002/ by kbr@chromium.org.

The reason for reverting is: The removal of Telemetry's retry logic wasn't the
cause of the intermittent crashes on the GPU bots.
