I think it's better to keep the value in bloomfilter index the same as that
after carbondata filed converter, so that we do not handle it specially for
building index as well as for querying which may waste the time.
The main problem maybe that we need to handle compatibility for old index
file before 1.5.0.
To be compatible with the previous version, we need to indicate the version
in some way.---
