retry! macro in response_data triggers unnecessary retry for object_exists

**Describe the bug** When using Bucket::object_exists the response_data call will trigger an unnecessary retry with warning logs in case of 404. **To Reproduce** Call Bucket::object_exists for a non-existant path. **Expected behavior** A 404 is not an unexpected result that should be retried in case of object_exists and it causes unnecessary delay and log clutter. **Environment** - lib version 0.37.0 (checked that 0.37.1 has nothing affecting this functionality)
