What were you trying to do that didn't work?

LEAPP preupgrade reports the  following as "Risk Factor: high(error)"

~~~
Risk Factor: high (error)
Title: DNF execution failed with non zero exit code. 
~~~

The cause of this issue can vary from

1. Conflicting files from third party RHEL7 packages with to be installed RHEL8 packages
2. Third party Python package replacement.
3.  Repository issues.

However, if leapp upgrade is attempted in such situation we end up with failure of dnf recorded in leapp-upgrade.log .

Since DNF is crucial for leapp to work this error message, if found, should be marked as an 'Inhibitor'

Please provide the package NVR for which bug is seen:

How reproducible:

100%

Steps to reproduce

1.  Follow the regular leapp procedure on system with preexisting issue for DNF 
   eg. Install sysvinit-tools-2.88-14.dsf.el7.x86_64 from Oracle which conflicts with procps-ng-3.3.15-6.el8.x86_64 over file /usr/sbin/pidof
2. See DNF execution error is reported by LEAPP preupgrade  report with 'high(error)' 
3. Proceed with Leapp upgrade to observe the IPU failure.

Expected results

 If YUM/DNF is unusable in a system that is undergoing IPU with leapp. Then it qualifies for a Risk Factor 'Inhibitor'.  'leapp-report.txt' should report this finding as 'inhibitor'

Actual results

Leapp preupgrade reports DNF execution failure error as "Risk factor:High(error)"
