Remove Catalog support

Summary

Remove Catalog support

Description

getCatalogTerm now returns an empty string instead of graph

I am unsure if this is the full extent of the changes required. A blanket search for methods that include the term catalog shows that the only logic that seems to have an actual function is in DatabaseMetaData describing the following:

public ResultSet getCatalogs() throws SQLException {
    LOGGER.info("Getting database catalogs.");
    return connection.getQueryExecutor().executeGetCatalogs(getConnection().createStatement());
}

This indicates to me that it's more related to a query regarding Catalogs that is a separate concept?

All tests ran and passed locally.

Did you get a chance to see if the catalog disappeared in dbvis?
