Bug Description

when booting an instance then wrong information of argument shown at cli, Here without with --flavor and --image we unable to boot a vm. So, these parameters should be positional not optional argument.

steps to replicate :

step 1:

$ nova help boot

Boot a new server.

Positional arguments:
  <name> Name for the new server

Optional arguments:
  --flavor <flavor> Name or ID of flavor (see 'nova flavor-list').
  --image <image> Name or ID of image (see 'nova image-list').

step 2:

$ nova boot vm_1

ERROR (CommandError): you need to specify a Flavor ID

Step 3

$ nova boot --flavor 42 vm_1

ERROR (CommandError): you need to specify at least one source ID (Image, Snapshot, or Volume), a block device mapping or provide a set of properties to match against an image

$ nova boot --flavor 42 --image <image-id>

then we able to boot a vm

expected result:

$ nova help boot

Boot a new server.

Positional arguments:
  <name> Name for the new server
  <flavor> Name or ID of flavor (see 'nova flavor-list').
  <image> Name or ID of image (see 'nova image-list').

The reason --image isn't a positional argument is because it isn't required.

See example 4 [1] where the command creates a bootable volume from an image before the instance boots. Here, --image is not specified.

I think the flavor is still required. Also novaclients documentation on what is needed isn't very useful. To figure out what is needed googling is often required, but it shouldn't be.
