> We propose to introduce `getComment()` method in `CatalogDescriptor`, and the
> reasons are as follows.
> 1. For the sake of design consistency, follow the design of FLIP-295 [1]
> which introduced `CatalogStore` component, `CatalogDescriptor` includes names
> and attributes, both of which are used to describe the catalog, and `comment`
> can be added smoothly.
> 2. Extending the existing class rather than add new method to the existing
> interface, Especially, the `Catalog` interface, as a core interface, is used
> by a series of important components such as `CatalogFactory`,
> `CatalogManager` and `FactoryUtil`, and is implemented by a large number of
> connectors such as JDBC, Paimon, and Hive. Adding methods to it will greatly
> increase the implementation complexity, and more importantly, increase the
> cost of iteration, maintenance, and verification.
>
> Set comment in the specified catalog. If the comment is already set in the
> catalog, override the old value with the new one.
