Upgrade should update changed FQN for MultiDelimiterSerDe in HMS DB.

While the parent change has does not cause this directly, but post upgrade the existing tables that use MultiDelimiterSerDe will be broken as the hive-contrib jar would no longer exist. Instead if the Hive schema upgrade script can update the SERDES table to alter the classname to the new classname, the old tables would work automatically. Much better user experience.
