Add Kopia SFTP support

[fastlorenzo]

Is your feature request related to a problem? Please describe. I'm currently using Kopia with SFTP backend to store snapshots, I see Kanister only supports S3, Azure and GCP.

Describe the solution you'd like It would be great if Kanister would support SFTP as a storage location for Kopia: https://kopia.io/docs/repositories/#sftp I believe this would require adding some parameters to the Kanister Profile. I'm not good enough at Go yet to be able to make a PR that wouldn't break anything else.

Describe alternatives you've considered Using S3 as a storage, but less convenient for me as I have a big SFTP backup storage available.

Environment Kubernetes Version/Provider: RKE2 1.25.3 Storage Provider: Rook CEPH / SFTP server for Kopia backups Cluster Size (#nodes): 3 master + 3 workers Data Size: variable, depends on the PVC to backup - couple of MB to ~250GB
