Title:
  nova-manage has several usage issues

Status in OpenStack Compute (Nova):
  Fix Released

Bug description:
  $ nova-manage --debug flavor create  --help
  usage: nova-manage flavor create [-h] [--name <name>] [--memory <memory size>]
                                   [--cpu <num cores>] [--root_gb <root_gb>]
                                   [--ephemeral_gb <ephemeral_gb>]
                                   [--flavor <flavor  id>] [--swap <swap>]
                                   [--rxtx_factor <rxtx_factor>]
                                   [--is_public <is_public>]
                                   [action_args [action_args ...]]

  positional arguments:
    action_args

  optional arguments:
    -h, --help            show this help message and exit
    --name <name>         Name of instance type/flavor
    --memory <memory size>
                          Memory size
    --cpu <num cores>     Number cpus
    --root_gb <root_gb>   Root disk size
    --ephemeral_gb <ephemeral_gb>
                          Ephemeral disk size
    --flavor <flavor  id>
                          Flavor ID
    --swap <swap>         Swap
    --rxtx_factor <rxtx_factor>
                          rxtx_factor
    --is_public <is_public>
                          Make flavor accessible to the public

  The above seems to me to imply that this is the correct way to invoke this command:
     nova-manage flavor create  --name m1.smoser --memory 512 --cpu 1 --root_gb 2 --ephemeral_gb 1 --is_public 1 --flavor 6

  However, doing that results in an error, complaining:
  4 arguments are missing: name, memory, vcpus, root_gb

  The correct way to specify name, memory, vcpus, root_gb is as positional args:
    nova-manage flavor create  m1.smoser 512 1 2

  That will actually work.

  To specify everything you want, you actually have to provide positional arguments with the following order:
   name memory vcpus root_gb [ephemeral_gb flavor_id swap rxtx_factor is_public]
  is_public must be something like 'true', 'false', 1, 0. arbitrary string will not work.

  So, as far as I can tell, then, there is no way to specify "extra
  specs", nor is there a way to specify public without specifying
  anything before it.

  So the 2 issues here are:
   * it really shoudl take flags for non-required variables so you can specify is_public without specifying ephemeral_gb
   * the usage is very confusing.
