Issue with leapp upgrade

[SuperSchramm]

This issue appears to be similar to the issue described in issue #15 however, that issue appears to be related to space and I do not have an issue with space on the system in question. I am getting the same message which looks to be related to the subscription-manager but I have removed subscription-manager, and any reference to it, and it is the same message using Oracle Linux or Rocky Linux.

I get the same error regardless of whether I use the --no-rhsm option or not.

I believe both this and #15 should be displaying the actual message for the error now, and not the e.stdout = e.stdout.encode('utf-8', 'xmlcharrefreplace') line.

@andrewlukoshko The encoding change in question change was released, right?
