Bad conditionals make Backup Domain Controllers evaluate Member Server rules rather than Domain Controller rules

[mfann-or]

Here is one example of many where the role needs to update this conditional to account for Backup Domain Controllers.

Issue:

Bad conditionals make Backup Domain Controllers evaluate Member Server rules rather than Domain Controller rules

Possible Solutions:

1. The conditional could use the same Ansible fact, but change the logic.

when:
  - "'domain controller' in ansible_windows_domain_role"

2. The conditional could use a different Ansible fact that is the same across Domain Controller types.

when:
  - ansible_os_product_type == "domain_controller"
