Code review comment for lp:~jshepher/nova/nova_manage_config_list

however, in the spirit of the example postconf.. it is nice for an administrator to have a function that just spits out all of the configuration paramaters with out any descriptions or defaults.. this is very nice when you just want to grep the running config for something:

Example:

# ./bin/nova-manage config list | grep -i glance
--glance_port=9292
--glance_host=$my_ip

# ./bin/nova-manage --help | grep -A2 -i glance
  --glance_host: glance host
    (default: '$my_ip')
  --glance_port: glance port
    (default: '9292')
    (an integer)
