use native-tracing versions of hyper and h2 (#591)

This branch patches the dependencies on hyper and h2 to unreleased
revisions that use tracing natively to emit diagnostics, rather than
log records (which we have to consume through an adapter layer).
Native tracing offers a small but noticeable performance improvement,
which should become more pronounced when enabling more diagnostics.
