Due to SERVER-53500, using the AsyncTry-until utility can lead to an invariant being hit in unpredictable places. Since SERVER-53500 will be difficult to diagnose and potentially unfeasible to fix, so in the meantime we can rewrite the AsyncTry utility to not use recursive futures, which are responsible for hitting the invariant. I've done a POC and confirmed this fixes the issues seen by SERVER-50656 on debug builds.
