Title:
  More heplful error message for the default role

Status in OpenStack Dashboard (Horizon):
  Fix Released
Status in OpenStack Dashboard (Horizon) folsom series:
  Fix Released

Bug description:
  Horizon requires a default keystone role to be defined in the
  settings. Depending on the installation guide they follow, users can
  easily end up with no "Member" group defined (the current default) and
  not be aware of the issue except for a few admin functions not
  working.

  When the default group doesn't exist and an admin user tries to e.g.
  edit a project, the message on the web UI will read:

  "Error: An error occurred. Please try again."

  And in the logs: "AttributeError: 'NoneType' object has no attribute
  'id'", e.g.

  [Wed Jan 16 01:15:29 2013] [error]     extra_context = {"form": self.action,
  [Wed Jan 16 01:15:29 2013] [error]   File "/opt/stack/horizon/openstack_dashboard/wsgi/../../horizon/workflows/base.py", line 360, in action
  [Wed Jan 16 01:15:29 2013] [error]     context)
  [Wed Jan 16 01:15:29 2013] [error]   File "/opt/stack/horizon/openstack_dashboard/wsgi/../../openstack_dashboard/dashboards/admin/projects/workflows.py", line 117, in __init__
  [Wed Jan 16 01:15:29 2013] [error]     redirect=reverse(INDEX_URL))
  [Wed Jan 16 01:15:29 2013] [error]   File "/opt/stack/horizon/openstack_dashboard/wsgi/../../openstack_dashboard/dashboards/admin/projects/workflows.py", line 113, in __init__
  [Wed Jan 16 01:15:29 2013] [error]     default_role = api.keystone.get_default_role(self.request).id
  [Wed Jan 16 01:15:29 2013] [error] AttributeError: 'NoneType' object has no attribute 'id'

  (see also bug #1084119).

  Horizon should provide a more specific and helpful error message, such
  as "Could not find default role %s in Keystone" in the logs and
  ideally on the UI as well.

  
  Steps to reproduce:
  1. Change the OPENSTACK_KEYSTONE_DEFAULT_ROLE in the local settings to a role name that doesn't exist
  2. Restart the webserver
  3. As an admin, go to the Admin Project tabs and click on Modify users
