Adaptive

How a store's query bound adapts to its write pressure, when neither wow.query.max-concurrent nor wow.stores.<name>.query.max-concurrent fixes it: pressing periods in a row halve it, down to floor; a calm period in which a query waited or was refused raises it by one, up to ceiling. wow.stores.<name>.query.adaptive.* overrides floor and ceiling for one store.

floor
