Lapin integration with bastion

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

``` use bastion_amqp::*; use bastion::run; use lapin::{Connection, ConnectionProperties, Result};

pub async fn consumer(addr: String) -> Result<()> { let conn = Connection::connect(&addr, ConnectionProperties::default().withbastion()).await?; // Note the with_bastion() here let channel = conn.createchannel().await?; // Rest of your program }

fn main() -> Result<()> { Bastion::init(); Bastion::start();

let addr = std::env::var("AMQP_ADDR").unwrap_or_else(|_| "amqp://127.0.0.1:5672/%2f".into());
run!(consumer(addr))

} ```
