Deprecate spark_resource_allocation_strategy_enabled property

[vermapratyush]

spark_resource_allocation_strategy_enabled is redundant and instead executor allocation and hash allocation strategy is to be used.

    > What is the right approach of deprecating/removing a property?

• We use @DefunctConfig annotation in a config class. Usually, we also rename the property to deprecated.XXX. Check FeatureConfig for examples. We don't usually delete the property directly.
• We have release note to tell users what config has the deprecated one migrated to
