Disable suggestion of v1 help for v2-specific subcommands

[Kyrylo Romanenko]

Currently when looking help for some subcommand using "--os-image-api-version 2" (explicitly of by default) we can see a prompt below:
Run `glance --os-image-api-version 1 help <command>` for v1 help.

This is false advice for v2-specific commands.
For example there is no "explain" and "task-create" and others on --os-image-api-version v1.

Execution of such commands will raise error message like:
$ glance --os-image-api-version 1 help task-create
'task-create' is not a valid subcommand

It would be good to disable suggestion of v1 help for v2-specific subcommands.

Checked on python-glanceclient (1.2.0).

    Disable suggestion of v1 help for v2 commands

    Currently the client suggests 'Run `glance --os-image-api-version 1
    help` for v1 help' at the end of every help message. This is could
    be confusing for a v2 only command.

    Therefore this patch disables it if the command does not exist in v1,
    while keeping the message on the 'glance help' results.
