This step is used for filtering out extra annotations so that they won't show

No additional links are expected to show on buildbot. An example is:
https://cros-goldeneye.corp.google.com/chromeos/healthmonitoring/
buildDetails?buildbucketId=8940161120910419584
But when users view the suite swarming task URL, they're expected to see
all its child tests and their results for further debugging, e.g.
https://chrome-swarming.appspot.com/task?id=3ee300326eb47a10&refresh=10
https://chrome-swarming.appspot.com/task?id=3ee30107bdfe7d10&refresh=10
It's bad behavior to filter out steps based on swarming output, which
means the buildbot interface is highly depending on the output of
run_suite_skylab.py in autotest. However, it is hard to insert annotations
independently (run_suite_skylab (python) cannot use the LogDog libraries
(Go)). Currently we're still relying on printing format
'@@@ *** @@@' and let builder running kitchen to interpret it automatically.
So this function is needed until we have better approaches to interact with
logdog.
