Goal: 

As a system administrator, I want to remove my RHC credentials (org_id/activation_key) from the system after registration so that it cannot be discovered by actors (good/bad) gaining access to the system.

Acceptance Criteria:

• Verify credentials are not clear text in the osbuild service definition
• Verify registration credentials are available for systemd service at first boot
• Verify system registers with RHC successfully
• Verify the credentials are removed from the system after registration
