Title:
  "openstack image list" fails when any images lack names

Status in python-openstackclient:
  New

Bug description:
  Some of our older images have their name field set to null. When I run
  "openstack image list" I only get the unhelpful response:

     '<' not supported between instances of 'NoneType' and 'str'

  Running "glance image-list" instead works correctly. Other openstack-
  client commands I run also execute correctly. I am running openstack-
  client version 3.12.0 on an Arch Linux box in a virtualenv.

  The error occurs in "lib/python3.6/site-packages/osc_lib/utils.py",
  line 531, in sort_items. My osc_lib is version 1.7.0.

  It seems to be caused by an attempt to sort the output by names,
  ascending:

  run(Namespace(columns=[], fit_width=False, formatter='table', limit=None, long=False, marker=None, max_width=0, name=None, noindent=False, page_size=None, print_empty=False, private=False, property=None, public=False, quote_mode='nonnumeric', shared=False, sort='name:asc', status=None))
     data = utils.sort_items(data, parsed_args.sort)
   File "/home/my_cool_username/src/openstack-client/3.12.0/lib/python3.6/site-packages/osc_lib/utils.py", line 531, in sort_items
     data = utils.sort_items(data, parsed_args.sort)
   File "/home/my_cool_username/src/openstack-client/3.12.0/lib/python3.6/site-packages/osc_lib/utils.py", line 531, in sort_items

  Personally, I don't mind using "glance image-list", but we are
  updating our documentation to tell users to use openstack-client. It
  would be best if they didn't receive cryptic failures when doing what
  we tell them to do :)
