Set child concurrency limit

Set the maximum number of simultaneous calls a child organization can run. Slots come from the reseller's shared pool. Increasing the limit deducts the delta from your pool and fails if you don't have enough slots. Decreasing the limit returns the delta to your pool immediately.
