Convert2RHEL tool has long suffered issues with individual packages causing yum transaction issues where we can't easily rollback due to the nature of the architecture we've been using. One way to handle this is by rewriting the amount of yum calls we do into a single transaction where we can handle the errors easier

Acceptance Criteria

• Yum calls are reduced from three calls into a single transaction
• Yum exceptions are handled in a way that makes Convert2RHEL less prone to error
