[metrics] Make metrics atomic ART metrics need to be able to be updated by multiple threads. We make this safe by making each metric value atomic. Note that this may be a scalability bottleneck if some metrics become heavily contended. If that turns out to be the case, we can explore other strategies, such as thread-local copies of contended metrics.
