SM: client cli help messages arent available for certain op

[Senthilnathan Murugappan]

Unable to figure out the help message for certain op like add/delete image
None of the below op provided the required syntax
1) server-manager delete help image
2) server-manager delete image -h
3) server-manager help delete image
4) server-manager delete image

Same applies for add image.

root@a2s36:~# server-manager delete help image
usage: server-manager delete [-h]
                             {server,cluster,image,tag,dhcp_subnet,dhcp_host}
                             ...
server-manager delete: error: invalid choice: 'help' (choose from 'server', 'cluster', 'image', 'tag', 'dhcp_subnet', 'dhcp_host')
root@a2s36:~# server-manager delete image

{
    "return_code": 8,
    "return_data": null,
    "return_msg": "Match key not present"
}
root@a2s36:~# server-manager delete image -h
usage: server-manager [--verbose] [--log-file LOG_FILE] [-q] [-h] [--debug]
