Description

BlobSize used by OakDirectory while storing the Lucene indexes was changed in [1] (and differs from 1.0 branch [3]) to ensure that blob get inlined in SegmentMK even when Segment MK is configured with external BlobStore. However this revision got missed from getting merged to 1.0 branch. Merging this now

1. would require reindexing of complete repo for new Lucene index to be created.
2. Further given the discussion in [2] we might want to continue to keep the index in BlobStore if configured
3. The gain in read performance can still be obtained once OAK-1724 is done
