The IndexWriter initialization might fail when other threads are updating the fileAndChunkRegion, which can be triggered by other normal operations (query, event listener, close, reindex, etc.). This doesn't happen often and, instead of propagating the exception to the caller and failing, Geode now catches it and returns null to let the callers retry.
- Added unit and distrbuted tests. - Return null instead of re-throwing the IOException while building the Lucene IndexWriter.
