Merge branch 'improveDeviceControllerDiag' into pu/integration

This states are rather meta infos about dc condition. Therefore the
where created and sent outside of superviseSystem()-method.
This commit should ensure that:
 - this states are sent to ISMAS
 - this states are inserted in machineEventSet in order to enable
   a reset in next diagRun
