Title:
  keystone did not start (ImportError: Class TemplatedCatalog cannot be
  found)

Status in devstack - openstack dev environments:
  New
Status in OpenStack Identity (Keystone):
  New

Bug description:
  After the commit ID 1ea9d50a2c828a3eb976e458659008a5461b1418 of Steve
  Martinelli (made on Thu Oct 2 12:57:20 2014 -0400), keystone service
  can no longer be started.

  Root cause:
    - At that commit ID, the class "TemplatedCatalog" is removed from the module keystone.catalog.backends.templated. Another class named "Catalog" also in that module is used.
    - However, DevStack script is not updated accordingly. Consequently, the file "devstack/lib/keystone" still points to the removed class "TemplatedCatalog".

  Proposal:
    - Change the file "devstack/lib/keystone" so that it points to the right class that is the "Catalog"

  Excerpt of the file "devstack/lib/keystone":

          # Configure ``keystone.conf`` to use templates
          iniset $KEYSTONE_CONF catalog driver "keystone.catalog.backends.templated.TemplatedCatalog"
          iniset $KEYSTONE_CONF catalog template_file "$KEYSTONE_CATALOG"

  
  Excerpt of the commit ID 1ea9d50a2c828a3eb976e458659008a5461b1418:

      Remove deprecated TemplatedCatalog class
      
      Use keystone.catalog.backends.templated.Catalog instead
