* 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 Signed-off-by: Jürgen Eckel <juergen@riddleandcode.com>
