Some ideas:
1, We have two catalog types, one is Native, the other is Non-Native;
2. For Native catalog, besides get table, the client is able to
create/drop/alter tables/partitions, so the catalog location uri is a must, we
can check it upon creating the catalog;
3. For Non-Native catalog, it's just a "mount" of external metadata
sources, no changes allowed;
4. Native can be changed to a Non-Native catalog, the Non-Native can be to
a Native catalog as well;
5. For default native hive catalog, the catalog location is
`hive.metastore.warehouse.dir`
6. Every thing a catalog needs is stored in CATALOG_PARAMS, including the
driver class, file system configurations, or extra jar files. The PARAM_VALUE
should be a clob instead of varchar in CATALOG_PARAMS.
Given these above, we don't need extra `metastore.warehouse.catalog.dir` or
others to determine the default catalog location, the location could be
anywhere, just make sure it's accessible by the Metastore.
