new release of rpm breaks tox that uses sysinv

[Al Bailey]

Brief Description
-----------------
A new version of rpm was released on pypi on Nov 4, 2021 and it breaks our ability to import sysinv in some environments.

Severity
--------
Critical

Steps to Reproduce
------------------
submit a code change to sysinv (or to any repo that runs zuul and tries to import sysinv as a dependency. ie: integ)

Expected Behavior
------------------
zuul should work

Actual Behavior
----------------
fails to install the rpm dependency, so zuul and tox fail

Reproducibility
---------------
100% (but its based on the nodeset and what is cached in its pip cache. Something cached from yesterday will still work)

System Configuration
--------------------
N/A

    Removing rpm as a dependency for sysinv

    A new version of the python module was released Nov 4
    which breaks pip installs in some environments.

    The rpm dependency is not directly required by sysinv
    and so it has been removed.

    The source code changes in this review are only included
    to ensure that all zuul targets are invoked.

Change has merged.

A similar fix was added for integ repo, but that fix just does not pull in sysinv, and therefore does not fail for this package
