Until now we've been recording and collecting the RHSM username and organization in their plain text form in the convert2rhel log files and the breadcrumbs files.

Users might perceive those values as sensitive or private information. Red Hat doesn't need this information for anything so it's better to not collect it at all.

Acceptance criteria:

• the RHSM credentials, specifically username and organization, are replaced with asterisks in:
  • the convert2rhel log files (/var/log/convert2rhel/convert2rhel.log, /var/log/convert2rhel/archive/convert2rhel-*.log),
  • the breadcrumbs files (/etc/migration-results, /etc/rhsm/facts/convert2rhel.facts).
