> HIVE-16723 gives the ability to have a custom MetastoreSchemaInfo implementation to manage
schema upgrades and initialization if needed. In order to make HiveSchemaTool completely agnostic
it should depend on IMetastoreSchemaInfo implementation which is configured to get the metastore
schema version information from the database. It should also not assume the scripts directory
and hardcode it itself. It would rather ask MetastoreSchemaInfo class to get the metastore
scripts directory.
