Hello,

we observe a failure in RPM job executed as part of Component CI for OSP 18

```
keystoneclient.tests.unit.test_cms.CMSTest.test_cms_verify_token_unscoped
-------------------------------------------------------------------------

Captured traceback:
~~~~~~~~~~~~~~~~~~~
Traceback (most recent call last):

File "/home/zuul/src/code.engineering.redhat.com/python-keystoneclient/keystoneclient/tests/unit/test_cms.py", line 122, in test_cms_verify_token_unscoped
self.assertTrue(cms.cms_verify(cms_content,

File "/home/zuul/src/code.engineering.redhat.com/python-keystoneclient/keystoneclient/common/cms.py", line 211, in cms_verify
raise subprocess.CalledProcessError(retcode, 'openssl', output=err)

subprocess.CalledProcessError: Command 'openssl' returned non-zero exit status 4.
```

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:

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.
