Updated ControlLoop component messages

Updated controlloop messages (ParticipantUpdate, ControlLoopUpdate,
ParticipantStatus) according to the following Wiki and added
implementation for the corresponding updates in runtime-controlloop and
participant components
https://wiki.onap.org/display/DW/The+CLAMP+Control+Loop+Participant+Protocol
