added connection loss handler, extended logging, mqtt msg updates (#400)
* added a bit of logging
* added update messages to mqtt (every second with a timestamp)
* added isConnectionOpen to the interface and analysis this during execution
* added connection loss handler and status check
* put some global objects into an objects to avoid inter service testing issues
* TestingLocker Mutex to RWMutex (increase performance)
* termintationMutex became a sync.RWMutex
* added logging to the mqtt mock client
* made monitor Mutex a RWMutex
* added Mutex protection to the numberOfElements varialbe
* added another Waiting block to the machine attestation methods (CI tests)
* had to adjust the test cases to the impact of that change.
