Thanks. If i am not wrong all these informations are already stored in nova db right ? Is there any other specific reason behind using this config file.

They are in the DB, yes. And the config drive is one of two ways for the instance to get the data.

It's the config drive, an ISO or VFAT filesystem with instance metadata and information like instance name, SSH key and floating IP. The same information that the instance can retrieve from the metadata API.
