Review Comment:
It can be useful for batch jobs as well. Like allocation ratio,
de-allocation ratio are also relevant in scaling-out/back only few executors at
a time. Especially in cases where Stages of a batch job has alternating
high/low tasks.
I restricted this behind `streamingDRAFeatureEnabled` initially for feature
distinction. I can modify the code to have this as a config which can be used
in traditional DRA as well.
