This is an automated cherry-pick of #53038

What problem does this PR solve?

During EBS snapshot backup, if any snapshots fail, the backup will be stuck indefinitely checking the snapshots that failed. Since we only run a single backup at a time, this also blocks subsequent backups.

Issue Number: close #53037

Problem Summary: Backup stuck when EBS snapshot failed

What changed and how does it work?

Update snapshot backup process to fail if it detects snapshots in failed state. We observe rare snapshot failures due to underlying EBS hardware issues.
