Add Support for S3 as Lock Storage Backend

[caiooliveiraeti]

Description:
This pull request introduces support for using Amazon S3 as a lock storage backend for ShedLock, leveraging S3's recently introduced conditional writes for concurrency control.

Motivation:
The addition of S3 as a lock storage backend allows users to take advantage of Amazon S3's scalability, availability, and now its conditional write operations. This makes S3 a compelling choice for distributed lock management in environments where S3 is already utilized.

Hi @lukas-krecan,

I just created a draft pull request to add support for Amazon S3 as a lock storage backend for ShedLock. The implementation uses S3 object metadata to store lock information such as (lockUntil, lockedAt and lockedBy). It also leverages S3's new conditional writes to concurrency control.

I believe this functionality could be valuable for users who already rely on Amazon S3 and need a scalable and reliable solution for distributed locks.

I’d love to hear your thoughts on this idea and if there’s anything I can adjust or improve in the code. I’m happy to discuss further and make any necessary changes!

Thank you for your time and consideration.

Best regards,
@caiooliveiraeti
