A tenant can't get his own global quota limit

[Chaoyi Huang]

If use user=demo, project_id=demo, openstack token issue to get the token for the demo user, and then execute the global quota limit show the limit for the tenant with the demo's project-id,

curl -H "Content-Type: application/json" -H "X-Auth-Token: $kb_token" http://127.0.0.1:8118/v1.0/$tenant_id/os-quota-sets/$tenant_id

File "/opt/stack/kingbird/kingbird/api/controllers/quota_manager.py", line 89, in get
    context, project_id)
  File "/opt/stack/kingbird/kingbird/db/sqlalchemy/api.py", line 112, in wrapper
    if not is_admin_context(args[0]) and not is_user_context(args[0]):
  File "/opt/stack/kingbird/kingbird/db/sqlalchemy/api.py", line 83, in is_user_context
    if not context.user or not context.tenant_id:
AttributeError: 'RequestContext' object has no attribute 'tenant_id'

The project_id=demo by default doesn't have the admin rights. So I'd guess that if you tried with admin it'll work

Sure, even demo has no admin role, but he should be able to know how much resources left could be used
