logstash s3 output doesn't support path-style url for s3 compatible storage.
It tries to connect to "< bucket>.< endpoint>"... instead of "< endpoint>/< bucket>".
Our internal s3 implementation currently only supports the path style, would be nice if logstash provides a switch to use path style.
Such as a shame that we are so close, yet so far! Blocked by such a small thing before logs can reach s3.
