Description

Feature Request / Improvement

We have reached good consensus on the https://github.com/apache/iceberg/pull/12584. Before merging this new Endpoint to the REST Catalog Specification, we want to implement core classes.

This issue depends on https://github.com/apache/iceberg/issues/13580 and targets the implementation of the Test Harness for the Iceberg REST Catalog. This doesn't need to be production ready implementation, storing Events in memory or spilling to local disk is OK.
