Remove extra parameter 'backup' in backup-create

The parameter 'backup' in backup-create is never read by our Trove API[1], so
I guess it's a extra key argument for history reason. In addition, the
'backup-copy' subcommand should be removed as well because it does not
support in current Trove API.
