Description

RocksDBConfigurableOptions mainly focus on the settings of DBOptions and ColumnFamilyOptions. The original design of this class is used to let user could configure RocksDB via configurations instead of programmatically implemented RocksDBOptionsFactory.
To make the minimal change, original options in RocksDBConfigurableOptions have no default value so that we would not make anything happen in DefaultConfigurableOptionsFactory just as before.
However, this make user not so clear of the option meaning with no default value, and we could consider change the relationship between them.
