Support of different AMQP Exchange types

Currently only `direct` AMQP exchange type is supported. It is [hardcoded](https://github.com/spiral/jobs/blob/3a53d827eecc0b16b20f263fcb21e4c4edadff7f/broker/amqp/queue.go#L226) and not configurable.
Need support for other [exchange types](https://www.rabbitmq.com/tutorials/amqp-concepts.html#exchanges)
