Tested using 3 Phabricator instances (one web, one taskmaster and one storage). The web and taskmaster tiers are directed at the Conduit API of the storage tier.
Applied D10400, D10401 and D10403 to Phabricator.
Ran `bin/repository lookup-users rTESTe9683b64d3283f0b2d355fdbf231bc918b5ac0ab` and saw the information returned (by making a request to `diffusion.querycommits` as the omnipotent user).
