Wrapper for hook functions

Variants

`Fn(Box<dyn Fn(&mut <M as Manager>::Type, &Metrics) -> HookResult<<M as Manager>::Error> + Sync + Send>)`

Use a plain function (non-async) as a hook

`AsyncFn(Box<dyn for<'a> Fn(&'a mut <M as Manager>::Type, &'a Metrics) -> HookFuture<'a, <M as Manager>::Error> + Sync + Send>)`

Use an async function as a hook
