fget_object has race

See original GitHub issue

When the fget_object is called twice it tries to download object into the same file and fails on the second call of the os.rename.

Expected behavior - the temporary filename shouldn’t have etag in the name and instead it should use uuid.uuid4().

I’m using https://pypi.org/project/filelock/ in the calling code to avoid that. I’m not sure if it makes sense to do it in the client, because filelock needs extra empty file for the lock.

@jahodfra fget_object() should work to resume partial download like other minio SDKs. Not working is an issue and will be fixed soon.

The idea of using <FILENAME>.<ETAG>.part.minio is like a web browser download/resume functionality i.e. the browser deals with fixed name <FILENAME>.part.
