admin extend tenant's volume but change admin self quota

[wuyuting]

When admin extend a tenant's volume, the tenant's quota-usage doesn't change, but admin self quota-usage have changed. The right practice is: extend whose volume, whose quota-usage should change.

This needs to be verified. Potential RC.

Mike, this is a valid bug. QUOTAS.reserve() uses context.project_id if 'project_id' isn't explicitly assigned. In this case, it belongs part of admin's quota usage instead of volume owner's.

Sorry, I've been away for some days. I'll fix it as soon as i can.

    Admin extends tenant's volume but change admin's quota

    When admin extends a tenant's volume, the tenant's
    quota-usage doesn't change. However, admin's quota-usage
    has changed. The right practice is: extend whose volume,
    whose quota-usage should be changed.
