System ROFL components

[peternose]

Currently, we only support RONL and ROFL components. The former are upgraded at the specified epoch, while the latter are upgraded immediately. In the future, we may add system ROFL components, which should upgrade together with the RONL components.

Solutions:

• Track attached (system) and detached (user) components, and return an error if a ROFL component transitions between these states.
• Introduce a new ROFL type, such as sROFL, SROFL, or SOFL, to represent system ROFL components that are upgraded alongside the RONL components.

The second solution currently appears cleaner, as it resolves issues that arise when a ROFL component transitions between states, such as when attached and detached components share the same ID.
