add application properties map to amqp_1 output

[DaniTulp]

Should populate the following in amqp_1 https://docs.oasis-open.org/amqp/core/v1.0/os/amqp-core-messaging-v1.0-os.html#type-application-properties.

Azure Service Bus or Event Hub use fields in this to provide deduplication. Internally we use it for routing messages to proper handlers as well without having to run multiple queues/hubs.
