Hello,

we observe a failure in RPM job executed as part of Component CI for OSP 17.1

```
==============================
Failed 1 tests - output below:
==============================

neutron.tests.unit.db.test_securitygroups_db.SecurityGroupDbMixinTestCase.test_create_security_group_no_quota
-------------------------------------------------------------------------------------------------------------

Captured traceback:
~~~~~~~~~~~~~~~~~~~
    Traceback (most recent call last):
      File "/home/zuul/src/code.engineering.redhat.com/neutron/neutron/tests/base.py", line 183, in func
        return f(self, *args, **kwargs)
      File "/home/zuul/src/code.engineering.redhat.com/neutron/neutron/tests/unit/db/test_securitygroups_db.py", line 94, in test_create_security_group_no_quota
        self.mock_quota_make_res.return_value = None
    AttributeError: 'SecurityGroupDbMixinTestCase' object has no attribute 'mock_quota_make_res'
```

What we do in the job, is:
– we fetch the spec file and install the RPM dependencies listed there,
– we install some missing RPMs identified (that should be in spec file probably, but they are not),
– we run the tests defined in tox.

The additional RPMs we install are listed here: https://github.com/RedHatCRE/znoyder/blob/6a7f3818d006680108c4b842c39c58215f894dea/znoyder/config.yml#L406

So, in essence, this is a tox job but with truncated requirement.txt and site-packages enabled.

You can use this change for debugging the issue.
