class method support with async

[b23r0]

I think it's very necessary to support asynchrony for class methods, in the form of something like this.

#[pymethods]
impl Test{

    #[new]
    pub fn new() -> PyResult<Test> {
        Ok(Test{})
    }

    // now report `async fn` is not yet supported for Python functions.
    async pub fn async_test(&mut self) -> PyResult<()> {
        Ok(())
    }
}

You can use the pyo3-asyncio crate for this. You have to make a normal method that returns a future object, similar to the examples at https://docs.rs/pyo3-asyncio/latest/pyo3_asyncio/index.html

I know that normal functions can implement async, but I hope class methods can too.

My understanding was that you can use pyo3-asyncio to implement #[pymethods] too.

I'm also going to close this, as a duplicate of #1632.
