The function Future bounds are slightly too restrictive. Namely: ``` <L::Service as Service<R>>::Future: Send + Sync + 'static, ``` The `BoxCloneSyncService` and `BoxCloneSyncServiceLayer` require: ``` S::Future: Send + 'static, <L::Service as Service<T>>::Future: Send + 'static, ``` Removing the `Sync` bound from the helper function: - Makes the helper function more useful (where futures are not `Sync`) - Is backwards compatible (loosening trait bound)

Mind adding a changelog entry? You can put a new Unreleased heading / section before the latest release.
