[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.
