Query Usage
Cumulative usage series for the pod. Each point is the running total of
the usage type at that timestamp, not the change within the bucket.
Pod-scoped queries carry every usage type except pod_count; requested
types that don't apply to the scope are ignored. Defaults to the last
24 hours; start must be within the last 90 days, and a future end
is clamped to now. The range divided by period must not exceed 1000
buckets.
