Title:
  horizon.tables.Column() raises an exception for a valid arguments
  combination

Status in OpenStack Dashboard (Horizon):
  Fix Released

Bug description:
  Say, if we pass some callable as first mandatory argument 'transform'
  of horizon.tables.Column __init__ method and do not provide
  'verbose_name' optional argument, __init__ fails with an exception
  (I've cut off irrelevant part of stacktrace):

    File "/home/tsufiev/develop/murano-dashboard/.venv/local/lib/python2.7/site-packages/horizon/tables/base.py", line 215, in __init__
      verbose_name = self.transform.title()
  AttributeError: 'function' object has no attribute 'title'

  This is clearly a bug, because horizon.tables.Column should be able to
  derive 'verbose_name' from 'transform' even if it is callable.
