Add SimpleReaderCache to lower indexing latency

Description

DefaultReaderCache for performance reasons, keeps IndexReader instances around for a duration (set by Freshness settings)
In cases where shorter indexing latency is desired, such cacheing strategy should be configured to be disabled.

call ZoieConfig.setReaderFactory(SimpleReaderCache.FACTORY) to turn this on.
