We have some metrics, e.g.:

- reported_by_chrome:allocated_objects_size

which show up as an aggregate of all individual reported_by_chrome:*:allocated_objects_size submetrics.

However, ssid pointed out that this particular aggregate is one that does not make much sense to look at.

Thus, we should probably audit the metrics emitted by memory-infra, and remove/filter out those which are not really meaningful to look at.
