Tested this between twousing 3 Phabricator instances of Phabricator,(one web, one taskmaster and one storage). using D10400 and another future diff I haven't diff'd yetThe web and taskmaster tiers are directed at the Conduit API of the storage tier.
Applied D10400 and D10403 to Phabricator. Applied D10402 to libphutil.
Ran `bin/repository lookup-users rTESTe9683b64d3283f0b2d355fdbf231bc918b5ac0ab` and saw the information returned (by making a request to `diffusion.querycommits` as the omnipotent user).
