### Feature Request / Improvement In the rest catalog client, we implemented the OAuth token refresh based on retry mechanism. https://github.com/apache/iceberg-python/blob/4148edb5e28ae88024a55e0b112238e65b873957/pyiceberg/catalog/rest.py#L126-L128 If there are concurrent calls to the rest client API, they may failed at the same time, then thousands of `_refresh_token` may be called. The behavior is likely acceptable with no exceptions, but it appears wasteful and not as expected. A potential solution is introducing a `threading.Lock` to protect the fetching process. Every call to `_refresh_token` should acquire the `Lock` first, and check whether the token is same as the expired token. -- This is an automated message from the Apache Git Service.
