please don't delete AwsHostNameUtils

[steveloughran]

Describe the feature

I've noticed that AwsHostNameUtils has a comment "TODO This isn't used for as many services as it supports. Can we simplify or remove it?".

It is used in the hadoop s3a client to work out the signing region of a bucket.

Removing it would break things and make people sad. 😢 (*)

Please leave, and ideally update the docs to say "this is used externally". Thanks.

(*) also it'd stop them dropping in updated SDK releases to hadoop installations and lead to bug reports on this project

Use Case

getS3RegionFromEndpoint() to continue to return region endpoints.
