Shouldn't the return type here be CatalogProvider?

Also is the Catalog type here correct?

Maybe this could have an additional catalog just to show it supports multiple ones.

Rationale for this change
We currently support the following kinds of providers: Catalog, Schema, and Table. There is one more in the heirarchy, CatalogProviderList. This adds the missing support.
What changes are included in this PR?
Following the same patterns as in CatalogProvider (and others) this adds support for Python and Rust based CatalogProviderList. It adds the option to register a new provider list with the session context.
Are there any user-facing changes?
New addition only.
