Add support for other s3 providers

You can configure another s3 provider by supplying the node_backup_s3_provider, node_backup_s3_access_key_id, node_backup_s3_secret_access_key, node_backup_s3_endpoint and optionally node_backup_s3_region. To use this type of service, you have to set the backup type to s3-rclone.
