Keystone v3 support for OpenStack Credential

[lewisface]

ISSUE TYPE

• Enhancement

SUMMARY

Keystone v3 requires project_domain_name to authenticate, but AWX openstack credential doesn't provide / request those in the credential templating.

Currently when the cloud.yml file is generated it is populated with:

clouds:
  devstack:
    auth:
      auth_url: 
      domain_name: 
      password:
      project_name:
      username:

Instead for v3 this should include "project_domain_name"

clouds:
  devstack:
    auth:
      auth_url: 
      domain_name:
      password:
      project_domain_name: 
      project_name:
      username:

Verified that the new field is usable from the UI, and with the unit test added I think we have good coverage for this new option. Going to close as verified
