[cosmos-admin] Admin tool for migrating Hive external tables

[frbattid]

This should be as "simple" as replicating the content of the MySQL metastore database.

Nevertheless, we could be more ambitious and a database per user could be created, containing each database each user's tables. The owner of each table is indicated when describing a table in an extended or formatted way. If the owner is root/hive, this is because the table was created by the Hive server on behalf of Cygnus; in that case the owner is prefixing the table name.

Some links helping on moving Hive tables:

It seems the location is needed; this is also given by the describe extended/formatted command.
