Add QueueType model

[geirolz]

This PR simply adds a model to type the possible queue types.
It also add some useful argument keys.

I was tempted to add the queue type as parameter of DeclarationQueueConfig with default as Classic.
The problem is that semantically, since it is part of the configuration, we should override the the args and this creates breaking changes.
We could consider to let the user override this config like this

    override def declareQueue(channel: AMQPChannel, config: DeclarationQueueConfig): F[Unit] =
      Sync[F].blocking {
        channel.value.queueDeclare(
          config.queueName.value,
          config.durable.isTrue,
          config.exclusive.isTrue,
          config.autoDelete.isTrue,
          Map(`x-queue-type` -> config.queueType.asString) ++ config.arguments
        )
      }.void
