Added io_work_scope RAII class to help with scoped lifetime of io_service event loop. Having io_context always increment the ref-count of active I/O operations whenever passed by-value to a function seems like unnecessary atomic operations when compared to selected usages of io_work_scope which generally only need creation for top-level operations.
