New simpler configuration api

[tsvetelintsonev]

The current configuration api is cumbersome with a lot of overload methods and large number of parameters. Using configuration via lambda expression will be more intuitive and easy to use

Log.Logger = new LoggerConfiguration()
        .Enrich.FromLogContext()
        .WriteTo.RabbitMQ((clientConfiguration, sinkConfiguration) => {
            clientConfiguration.Hostnames     = _config["RABBITMQ_HOSTS"];
            clientConfiguration.Username     = _config["RABBITMQ_USER"];
            clientConfiguration.Password     = _config["RABBITMQ_PASSWORD"];
            clientConfiguration.Exchange     = _config["RABBITMQ_EXCHANGE"];
            clientConfiguration.ExchangeType = _config["RABBITMQ_EXCHANGE_TYPE"];
            clientConfiguration.DeliveryMode = RabbitMQDeliveryMode.Durable;
            clientConfiguration.RouteKey     = "Logs";
            clientConfiguration.Port         = 5672;
            sinkConfiguration.TextFormatter = new JsonFormatter();
        })
        .CreateLogger();

In order to support configuration via app settings binding the following api can be added

var config= new RabbitMQConfiguration
        {
            Hostnames       = _config["RABBITMQ_HOSTS"],
            Username        = _config["RABBITMQ_USER"],
            Password        = _config["RABBITMQ_PASSWORD"],
            Exchange        = _config["RABBITMQ_EXCHANGE"],
            ExchangeType    = _config["RABBITMQ_EXCHANGE_TYPE"],
            DeliveryMode    = RabbitMQDeliveryMode.Durable,
            RouteKey        = "Logs",
            Port            = 5672
        };

        Log.Logger = new LoggerConfiguration()
        .Enrich.FromLogContext()
        .WriteTo.RabbitMQ((clientConfiguration, sinkConfiguration) => {
            clientConfiguration.From(config);
            sinkConfiguration.TextFormatter = new JsonFormatter();
        })
        .CreateLogger();
