S3 PutObjectRequest doesn't detect .gz files and set content-type

[leccelecce]

Expected Behavior

In the V1 SDK, PutObjectRequest would set the content-type to application/x-gzip if I uploaded a .gz file.

Current Behavior

In V2, it sets to the default application/octet-stream

Possible Solution

It looks like this was more broadly looked at in #442 and a mime.types file was created, but this has no mapping for gz

Steps to Reproduce (for bugs)

client.putObject(PutObjectRequest.builder().bucket(awsBucketName).key(key).build(), RequestBody.fromFile(localFile));

(in the above instance, localFile is a Path to a file ending in .gz)

Your Environment

• AWS Java SDK version used: 2.1.0
• JDK version used: OpenJDK 11.0.1
• Operating System and version: Docker: openjdk:11-jre-slim

As per iana official list, the content-type would be application/gzip. It differs from v1. I made a put call and it works fine. Do you have any issues with it?
