extend input bindings with binding expressions to wire up related output bindings

[KaiWalter]

Azure Functions has this notion of binding expressions which allows to wire up input bindings (in Azure Functions terminology) with a trigger binding.

C# Sample: Correlation Id or queue message is used to lookup document (large message payload) from Blob Storage:

        [FunctionName(nameof(DistributeInvoice))]
        public static void DistributeInvoice(
            [ServiceBusTrigger(
                "invoice-queue",
                Connection = "sbConnection")] Microsoft.Azure.ServiceBus.Message messageHeader,
            [Blob(
                "payloads/invoice/{correlationId}",
                FileAccess.Read,
                Connection = "payloadStorage")] string payloadIn,
            ILogger log,
            ExecutionContext context)
        {

this would give us what we try to achieve with the Blob Get outbound binding #469 in one sweep
