> Currently, FSInputModule exposes readersCount property which is used for static partitioning of BlockReader.
> To support dynamic partitioning, following additional properties will be exposed.
> 1. minReaders = minimum number of readers for dynamic partitioning.
> 2. maxReaders = maximum number of readers for dynamic partitioning.
> 3. repartitionCheckInterval = time in seconds for checking if repartition is required.
> minReaders, maxReaders will set respective property on BlockReader.
> repartitionCheckInterval will set intervalMillis property on BlockReader after converting from seconds to milliseconds.
