/// <param name="activateHandlers">The bus will use this to construct handlers for received messages.</param>
/// <param name="sendMessages">Will be used to send transport messages when you send, publish, and reply.</param>
/// <param name="receiveMessages">Will be used to receive transport messages. If the bus is configured to run with multiple threads, this one should be reentrant.</param>
/// <param name="storeSubscriptions">Will be used to store subscription information. Is only relevant if the bus is a publisher, i.e. it publishes messages and other services assume they can subscribe to its messages.</param>
/// <param name="storeSagaData">Will be used to store saga data. Is only relevant if one or more handlers are derived from <see cref="Saga"/>.</param>
/// <param name="determineMessageOwnership">Will be used to resolve a destination in cases where the message destination is not explicitly specified as part of a send/subscribe operation.</param>
/// <param name="serializeMessages">Will be used to serialize and deserialize transport messages.</param>
/// <param name="inspectHandlerPipeline">Will be called to inspect the pipeline of handlers constructed to handle an incoming message.</param>
/// <param name="errorTracker">Will be used to track failed delivery attempts.</param>
/// <param name="storeTimeouts">Optionally provides an internal timeout manager to be used instead of sending timeout requests to an external timeout manager</param>
