objects: add missing prog parameter in subcommands

The specific subcommand name is missing in some of the subcommands help
message. For example:

	$ ogcli list hardware
	usage: ogcli [-h] --client-ip CLIENT_IP
	ogcli: error: the following arguments are required: --client-ip

Fix this by adding the missing prog= parameter so argparse use this
instead of argv[0]. If no prog parameter is specified then argv[0] is
printed (i.e: "ogcli").
