Implement uploading functionality for status page storage client for AWS S3

What does this MR do?

Part of #205168 (closed).

This MR implement the most minimal status page storage client for AWS S3 which just handles uploading objects.

The S3 client returns platform-agnostic data to allow an easier way adding a more generic interface later.

Future MRs will implement the actual usage of this S3 client. Currently, the S3 client is only used in PoC MR.
