[AB-184] adding various metrics to the system, organizing imports, changing some transactional behaviour

adding okhttp metrics, split bot service into multiple services (guild, message), unified some places that services are used in order to interact with the api, and not directly the objects (this is to make it easier for metric to be accurate)
