Volume deletion should be idempotent
- Describe* calls should return `aws.Error` so caller can handle individual errors. `aws.Error` already has enough context (`"InvalidVolume.NotFound: The volume 'vol-0a06cc096e989c5a2' does not exist"`)
- Deletion of already deleted volume should succeed.

Fixes: #60778
