argparse support for cfg
The main cfg API change is that CONF() no longer returns the un-parsed
CLI arguments. To handle these args, you need to use the support for
positional arguments or sub-parsers.
Switching nova-manage to use sub-parser based CLI arguments means the
following changes in behaviour:
- no more lazy matching of commands - e.g. 'nova-manage proj q' will
no longer work. If we find out about common abbreviations used in
peoples' scripts, we can easily add those.
- the help output displayed if you run nova-manage without any args
(or just a category) has changed
- 'nova-manage version list' is no longer equivalent to
'nova-manage version'
