Lapin integration with tokio

This crate integrates lapin with tokio by using tokio's executor inside of lapin for its internal operations and for consumer delegates.

``` use tokio_amqp::*; use lapin::{Connection, ConnectionProperties, Result};

[tokio::main]

async fn main() -> Result<()> { let addr = std::env::var("AMQPADDR").unwraporelse(|| "amqp://127.0.0.1:5672/%2f".into()); let conn = Connection::connect(&addr, ConnectionProperties::default().withtokio()).await?; // Note the with_tokio() here let channel = conn.createchannel().await?;

// Rest of your program

} ```
