Description

This PR updates the version of the AWS SDK from v1 to v2. The version 1 has been deprecated for some time now.

I have ran the following manual test:

  1. Create a Vitess cluster (1 unsharded keyspace) from the main branch
  2. Insert some data
  3. Backup the cluster into AWS S3
  4. Teardown the cluster
  5. Create a Vitess cluster (same config) from the migrate-to-s3-v2 branch (with --restore_from_backup)
  6. Restore from the previous backup
  7. Observe that the inserted data shows up after restoring
  8. Take another backup on AWS S3
  9. List all available backup on AWS S3
  10. Restore the cluster from the latest backup (using RestoreFromBackup)
  11. Remove the first backup we did (the one from main) from AWS S3
  12. Teardown the cluster
  13. Create another Vitess cluster (same config) from the main branch (with --restore_from_backup)
  14. Observe that the inserted data shows up after restoring

This test ensures that we can upgrade: old backups will still work with the new code, and that we can downgrade: new backups will work with the old code. While making sure that no config/flag change is needed between the two code version. It also checks that the GetBackups and RestoreFromBackup vtctldclient commands work.

Using context.Background() is a side-effect of the issue described in #14188. Upgrading to the SDK V2 does not fix it, the issue is rooted in how we handle the context and the goroutines. I started investigating the issue a bit deeper and will continue in a subsequent PR.

This code is going to be called regardless of s3 or other storage backend. Why this change?

data is a already a slice of bytes, I saw it while debugging something and thought I'd remove the useless conversion, I can revert if you want
