Improve messaging around Logging

After a failed deployment, we need to make it more clear what might be the issue.

• Problem with undercloud?
• Problem with the deployment?
• Problem with an application?

Would most likely be the deployment, but the wording should be super clear.

Might be nice to just have an overview of any failures for the user to see here.

If it were a Red Hat install, this should probably point to the SOS Report.
