fixes prometheus#231. this introduces a new method to `Family<S, M, C>` to help alleviate the risk of deadlocks when accessing multiple series within a given metrics family. this returns a plain `M`, rather than the `MappedRwLockReadGuard<M>` RAII guard returned by `get_or_create()`. a test case is introduced in this commit to demonstrate that structures accessing multiple series within a single expression will not accidentally create a deadlock.
