Ref T13677. Drydock has a hard-coded and fairly arbitrary limit which prevents a resource pool from growing more than 25% at once.

This is vaguely reasonable for resources which allocate quickly, but suffocating for slower resources. It's also wholly arbitrary, and the "one per lease" limit introduced in D21807 should do a better job of covering the same ground while generally being more reasonable, expected, and predictable.

Ran Drydock allocations without the throttle, saw faster pool growth.
