Add more feature flags for tuning dynamic persistence throttling
Adds the following feature flags:
* `persistence-throttling-window-size` for setting min/max window size
to the same value, effectively creating a static throttle policy.
* `persistence-throttling-ws-resize-rate` for controlling the rate
at which the dynamic throttle policy resizes its window.
