Description

Currently, we store avro schema string in commit metadata inside a map structure - extraMetadata. We are building logic where we expect this avro schema to be present in metadata. It would be cleaner if we store avro schema in the same way we store write-stats in commit metadata. 

We need to use MigrationHandler framework to handle upgrade.
