Initial Package Publish is Delayed

[JaggerJo]

Hey 👋

First, thanks for building a new OSS .NET MQTT library. I really like the simple implementation.

I've noticed that after creating and connecting a client the first publish can be delayed by ~500ms. I think this is because of the delay introduced here, where sending is delayed until a connection is established.

hivemq-mqtt-client-dotnet/Source/HiveMQtt/Client/Connection/ConnectionManagerTasks.cs

Line 131 in 04593d4

await Task.Delay(500).ConfigureAwait(false);

This is usually not a problem, but for certain scenarios (component tests that involve a local MQTT server) it would be nice if the delay was shorter.

Hi @JaggerJo! I think that is do-able. I'll see if I can release something soon. Thanks for pointing this out!
