Feature request: provide mock ability for `Catalog` trait

[dentiny]

Is your feature request related to a problem or challenge?

Hi team, I'm using catalog heavily in my daily dev and testing.

Catalog is "proxy" / "library" / whatever-you-call-it to interact with iceberg tables, which heavily works with IO operations. I would like to know, if you think it possible / easy to provide a mock catalog (i.e. via crates like mockall) to provide mock functionality, so I could inject errors to do chaos testing?

Describe the solution you'd like

Provide mock ability for Catalog trait.

I could work-around by having another wrapper around, but that's awkward to maintain.

Willingness to contribute

I would be willing to contribute to this feature with guidance from the Iceberg Rust community
