Cliff does not allow override of some arguments

[Terry Howe]

argparse does not have a way to get and modify arguments set by a parent class, so it would be convenient if cliff allowed arguments to be override for the default value and perhaps the help text. OSC for instance uses a slightly different usage of --debug where it sets verbose_level=3 if --debug. The help text for --debug does not say that.

Also, the default value for --debug is False and this makes it so OCC cannot override the value. If it was set to None, OCC would set it out of the file.

    Override the debug default and help text

    Cliff sets the default debug value to False and this makes it
    impossible to override debug with OCC. If we set the default to
    None, we can override debug in clouds.yaml. Also, OSC changes
    the meaning of --debug, so modify the help text.
