running fuel client with out any args doesn't print help

[Andrew Woodward]

running fuel client with out any args doesn't print the help usage, instead it only prints a short message

actual result:

[root@nailgun ~]# fuel
usage: fuel [optional args] <namespace> [action] [flags]
fuel: error: too few arguments

expected result:

[root@nailgun ~]# fuel
usage: fuel [optional args] <namespace> [action] [flags]

optional arguments:
  -h, --help show this help message and exit
  -v, --version show program's version number and exit
  --fuel-version show Fuel server's version number and exit
  --debug prints details of all HTTP request
  --os-username USER credentials for keystone authentication user
  --os-password PASSWORD
                        credentials for keystone authentication password
  --yaml prints only yaml to stdout
  --json prints only json to stdout

    Show help usage by default for fuelclient

    Also added 'fuel help' as a useful option
    (same as fuel -h) to show usage as well.
