Description of problem:

Over an OpenStack 7.0 installed by OSP-D, the heat tempest tests with unauthorized error due to the wrong value being parsed at the creation of tempest.conf file

Version-Release number of selected component (if applicable):
Director

How reproducible:
Create the tempest.conf file using --deployer-input provided from deployment. It'd contain a wrong value of stack_owner_role = heat_stack_user when it should be stack_owner_role = heat_stack_owner.

This is created by:
https://github.com/rdo-management/python-rdomanager-oscplugin/blob/master/rdomanager_oscplugin/v1/overcloud_deploy.py#L656


Steps to Reproduce:
1. Run orchestration tempest tests with provided tempest.conf

Actual results:

The test fails with the following error:

Traceback (most recent call last):
  File "/home/stack/tempest/tempest/api/orchestration/stacks/test_environment.py", line 36, in test_environment_parameter
    environment=environment)
  File "/home/stack/tempest/tempest/api/orchestration/base.py", line 75, in create_stack
    files=files)
  File "/home/stack/tempest/tempest/services/orchestration/json/orchestration_client.py", line 56, in create_stack
    resp, body = self.post(uri, headers=headers, body=body)
  File "/usr/lib/python2.7/site-packages/tempest_lib/common/rest_client.py", line 252, in post
    return self.request('POST', url, extra_headers, headers, body)
  File "/usr/lib/python2.7/site-packages/tempest_lib/common/rest_client.py", line 629, in request
    resp, resp_body)
  File "/usr/lib/python2.7/site-packages/tempest_lib/common/rest_client.py", line 672, in _error_checker
    raise exceptions.Forbidden(resp_body)
Forbidden: Forbidden


Expected results:

The test should pass, they do with this line in tempest.conf:

[orchestration]
stack_owner_role = heat_stack_owner
