openstack cli - show available columns

[Dan Kirkwood]

using the openstack python cli, column names are not always obvious and must match exactly what the tool expects (including matching case). When no column names given on the cmd line match, print a more useful error message with the names of available columns. e.g.

   $ openstack server list -f value -c name -c image

   No recognized column names in [u'name', u'image'].

with a small change, this could list the known columns:

   No recognized column names in [u'name', u'image']. Recognized columns are ('ID', 'Name', 'Status', 'Networks', 'Image Name').

I see that this actually should have been filed against `cliff`, and I have the fix in-hand. Can it be reassigned?

[Steve Martinelli (stevemar)]

@dangogh, certainly, and yeah, its a cliff bug. for the record, bugs against the CLI are filed against "python-openstackclient", i have no idea what "openstack-user-stories" is :)
