Bug 1574431

Description of problem:

It is possible to successfully create quota entry with any text word instead of valid project ID. This is misleading for customers: they successfully create quotas with project names instead of project IDs, but those quotas are not enforced.


How reproducible:

The following command may look like a command that adds a quota for admin tenant, but instead it creates a dummy record in cinder DB:

cinder quota-update --volumes 3 admin

MariaDB [cinder]> SELECT * FROM quotas WHERE project_id="admin";
+----+---------------------+------------+------------+---------+------------+----------+------------+-----------+
| id | created_at          | updated_at | deleted_at | deleted | project_id | resource | hard_limit | allocated |
+----+---------------------+------------+------------+---------+------------+----------+------------+-----------+
|  6 | 2018-05-03 09:41:49 | NULL       | NULL       |       0 | admin      | volumes  |          3 |         0 |
+----+---------------------+------------+------------+---------+------------+----------+------------+-----------+


Here is an entry for valid cinder quota:

MariaDB [cinder]> SELECT * FROM quotas WHERE project_id="602c2a16e060483f997193a314d0b9c7" AND resource="volumes";
+----+---------------------+---------------------+------------+---------+----------------------------------+----------+------------+-----------+
| id | created_at          | updated_at          | deleted_at | deleted | project_id                       | resource | hard_limit | allocated |
+----+---------------------+---------------------+------------+---------+----------------------------------+----------+------------+-----------+
|  9 | 2018-05-03 10:02:00 | 2018-05-03 10:09:06 | NULL       |       0 | 602c2a16e060483f997193a314d0b9c7 | volumes  |          9 |         0 |
+----+---------------------+---------------------+------------+---------+----------------------------------+----------+------------+-----------+


Actual results:

cinder creates misleading quota entries in DB


Expected results:

cinder asks to use valid project_id
