This also can go away, assuming we can use Buildbucket for CL Actions, which I think we agreed should work fine?

Eventually but we will have to write to CIDB for awhile while we wait for other teams who are reading from CIDB to migrate off. Dhanya has a plan for this that I just reviewed with him today so it might be good to chat with him about it.

Also, this stage does more than just write to CIDB: http://cs/chromeos_public/chromite/cbuildbot/stages/report_stages.py?l=237&rcl=cde48580e93da01999f0032e32ebf7fbca0e474e . It also writes metadata out so we need to evaluate who is using that and see if we can stop doing that.
