Current organization usage and limits for the active billing period

Return the org-wide usage for the current calendar month and configured limits.

Usage is aggregated across all members of the organization (limits are org-level) for the current calendar-month period and resets on the first of each month. Simulation usage is a single figure; compute usage is broken down by job type with the total in compute.usage. All values are in hours; a None limit means that usage type is unconstrained.
