    Skip instance name templating in API cell
    
    There is a template called multi_instance_display_name_template
    which is used when a user creates multiple instances in one request.
    Template is used to assign display name to instance and
    by default looks like "%(name)s-%(count)d".
    
    If cells are enabled template was applied two or more times (in API cell
    and in child cell).
    
    Changes exclude template applying in API cell.
    Also tests are changed to check display name in default environment
    and cells environment.

Title:
  Creating multiple instances with a single request when using cells
  creates wrong instance names

Status in OpenStack Compute (nova):
  Fix Released

Bug description:
  When creating multiple instances with a single request the instance name has the format defined in the "multi_instance_display_name_template" option.
  By default: multi_instance_display_name_template=%(name)s-%(count)d
  When booting two instances (num-instances=2) with the name=test is expected to have the following instance names:
  test-1
  test-2

  However, if using cells (only considering 2 levels) we have the following names:
  test-1-1
  test-1-2

  Increasing the number of cell levels adds more hops in the instance name.
  Changing the "multi_instance_display_name_template" to uuids has the same problem.
  For example: (consider <uuid> a random uuid)
  test-<uuid1>-<uuid1>
  test-<uuid1>-<uuid2>
