Review Comment:
Thanks for working on this patch @Tejaskriya. Most request header
validations are performed in
[StringToSignProducer.java](https://github.com/apache/ozone/blob/master/hadoop-ozone/s3gateway/src/main/java/org/apache/hadoop/ozone/s3/signature/StringToSignProducer.java)
during signature validation.
Would it make sense to move header pre-reqs for multi-part uploads including
requirements for Content-Length and Content-Encoding as per [AWS
docs](https://docs.aws.amazon.com/AmazonS3/latest/API/sigv4-streaming.html) to
a validation function in StringToSignProducer.java?
