tweak(backup): switch S3 storage class to STANDARD_IA

[tabarra]

This adds the flag that specifies that the S3 object should use the "Standard - Infrequent Access" class, which is 45% cheaper than the standard one.

Caution

I know that doing a s3:PutObject with a new storage class works and does not break compatibility, but I have not compiled and tested this PR.

Changes

• Changed the MinIO command to add the --storage-class flag, as described in https://min.io/docs/minio/linux/reference/minio-mc/mc-cp.html#mc.cp.-storage-class

Issues

• Closes S3 Backups should use the "Infrequent Access" storage class. #5670

It was a mistake, sorry. I recreated the next branch and it auto-closed this PR.

This is a good addition, but unfortunately, we cannot hardcode it as it fails if the storage class is not available. So I will add a small input box where you can set the storage class manually.

1. If it's empty, no --storage-class is used in the mc command
2. If not, add the right option.

This needs:

• A db migration (add a storage_class to ScheduledDatabaseBackup model).
• UI changes in backup-edit.blade.php.
• Based on the input, define the right mc command.

Can you please do these instead of the hardcoded command?

@peaklabs-dev I mean, this is still important... I just didn't have the time to set up the dev env to apply the required changes and test it out.
