 * Circuit breaker parameters.
 * Analog to real aviation circuit breakers these parameters
 * allow to disable subsystems. They are not supported as standard
 * operation procedure and are only provided for development purposes.
 * To ensure they are not activated accidentally, the associated
 * parameter needs to set to the key (magic).
