This is a bug, as tenant and user is maintained by keystone and quota are
stored in nova db, so it has the cleanup problems.

> Hi guys,
> I am working on bug #1449498, <the command “nova quota-show” Should not
> display the quota of a user has been deleted>.
> Reproduction steps w/ devstack and Liberty:
> 1) create a tenant bug_test
> 2) create a user test1 in tenant bug_test
> 3) update the quota instances of test1 as 5 (the default instances value
> is 10)
> 4) delete user test1
> 5) query the quota information for user test1 in tenant bug_test
> in step5, the expected result should indicate user test1 doesn't exist,
> while nova returned the deleted user test1's quota infomation with
> instances as 5.
> After investigation, it is found that quota_get_all_by_project_and_user()
> and quota_get_all_by_project() will invoke model_query(context, model,
>                 args=None,
>                 session=None,
>                 use_slave=False,
>                 *read_deleted=None*,

> While the model_query() doesnot work as expected, that is, in case a user

> associated with the deleted user will also be returned.
> I am not sure if this is a design behavior or this could be problem in
