Description

Ozone replication type is set based on the x-amz-storage-class HTTP header in s3g thanks to HDDS-712.

If header is not set the default replication type will be used (RATIS/3).

Unfortunately some tricky clients (such as the goofys FUSE driver) sends an empty header.

This patch fixes the behaviour to use the default replication type in case of an existing but empty header.
