Function ockam_core::compat::future::poll_once

pub fn poll_once<'a, F, T>(future: F) -> Result<T>
where
    F: Future<Output = Result<T>> + Send + 'a,

Polls a future just once and returns the Result

This is only used for some tests and it is hoped that we can remove it if, at some point, this makes it into core::future
