* set keepalive ping
* made mutex more granular
* avoid using app.Logger to have a consistent log from the beginning
* made lazyLoading local to the module
* fixed ticker bug so that the tasks are executed in an endless loop
* fixed timezone bug of Add Participant. only validator local time is used not the timestamp from the mqtt messages as these might come from a different time zone (resulted in delayed deletion from the activeActors DB)
* improved connection management for the monitor
* added a watchdog task to restart the monitor in case of connection loss (every 2 min)
* removed obsolete SetContext function/interface
* removed obsolete time conversion method

* added a MqttMonitor module with levelDB and periodic cleanup
* initialized in the app
* passed to dao keeper
* added conversion methods (string2unixtime, byte ToJSON)
* removed obsolete keeper code
* maded RDDLToken.Factor public
* added explicit mqtt client to the monitor module
* restart mqtt connection in mqttmonitor on connection loss
* adjusted mqttmock structure to be compatible
* added some linter exclusions to let the monitor tool pass
* created a MockMqttMonitor interface and mock object
* used this to pass tests
* made the MockMqttMonitor a global object so that it can be easily mocked
* removed MockMqttMonitor from the app/keeper initialization
* adjusted test cases to register "active machines" to the mqttmonitor
* added mutex in mocks to protect against data races
* defined mocks for the dao tests
* clear separation between interface and mqtt-Monitor
* added another waiting block to ensure the tx went through (multi-threading issue, race condition) during tests this failed sometimes
* added memstorage to test instead of a file based DB
