Synchronize ticker and histogram metrics for Java API (#4733)
Summary: Updating the `HistogramType.java` and `TickerType.java` to expose and correct metrics for statistics callbacks. Moved `NO_ITERATOR_CREATED` to the proper stat name and deprecated `NO_ITERATORS`. Pull Request resolved: https://github.com/facebook/rocksdb/pull/4733 Differential Revision: D13466936 Pulled By: sagar0 fbshipit-source-id: a58d1edcc07c7b68c3525b1aa05828212c89c6c7
