### Summary

As of now, we only retry galaxy API requests when they result in error codes defined within `RETRY_HTTP_ERROR_CODES`.

Some times there are also transient timeout errors, that are not represented by these status codes, and instead raise a `TimeoutError`.

Evaluate extending the function used by `should_retry_error`, to also retry on `TimeoutError`.
