Review Comment:
> for the external catalogs dbtype should be "REMOTE", right?
I don't think so. `REMOTE ` dbtyp was introduced by HIVE-24396 data
connector. If we implement all tasks about federated catalog, **we can
deprecate data connector**. Because the data connector can only map external
databases to internal databases by manually creating remote databases one by
one to query external data sources, like this:
`CREATE REMOTE DATABASE db_map_mysql USING mysqlconnector with
DBPROPERTIES("connector.remoteDbName"="testmysqldb");`
whereas the federated catalog can retrieve all external databases at once
without the need to manually create remote databases, once we create a catalog.
> It seems that we always hardcode "NATIVE" and below condition never
returns true
If you create a remote database with a specified dataconnector, this
condition will return true.
