fix(ategcs): stop calling CreateBucket on every PutObject

[Brandon Jacobs (brandonrjacobs)]

Summary

s3Client.PutObject called CreateBucket before every upload. Convenient against local dev backends like rustfs/minio where buckets may not pre-exist, but against managed S3-compatible backends the caller typically lacks s3:CreateBucket, so each snapshot upload paid for a 403 in added latency and audit-log noise.

For local kind dev, add a one-shot Job alongside the rustfs Deployment that creates the ate-snapshots bucket once at install time.

Validation

Verified locally with a kind cluster:

• Applied namespace + manifests/ate-install/kind/rustfs.yaml
• rustfs-bucket-init Job retried once while rustfs came up, then created ate-snapshots
• aws s3api list-buckets against rustfs returns ate-snapshots

Hmm, perhaps we should make the kind environment also pre-create the bucket on install and drop this entirely.

In general we want the CI environment to look like production where possible.

Yeah that would make sense; i wasn't sure what the general idea was but that works as well if we want to go that route.

Benjamin Elder (@BenTheElder) I dropped the create call and added it to kind setup if we want to go that way instead.

Thank you!

Unfortunately as far as I know we require the CLA currently.

Otherwise aside from one minor comment I am +1

[Brandon Jacobs (brandonrjacobs)]

Working on getting that resolved!
