We reviewed the design of this feature at the summit with CERN and HP
teams. Centralized quota storage in Keystone is an anticipated feature, but
there are concerns about adding quota enforcement logic for every service
to Keystone. The agreed solution is to add quota numbers storage to
Keystone, and add mechanism that will notify services about change to the
quota. Service, in turn, will update quota cache and apply the new quota
value according to its own enforcement rules.

More detailed capture of the discussion on etherpad:

Re this particular change, we plan to reuse this API extension code, but
extended to support domain-level quota as well.

Best regards,
