Description of problem:
Example dr-rhv-failover.yml and dr-rhv-failback.yml playbooks[1] have wrong identation which prevents them from working.

Current dr-rhv-failover.yml:

---
  - name: Failover RHV    # wrong identation  
    hosts: localhost      # wrong identation
    connection: local     # wrong identation
  vars:
    dr_target_host: secondary
    dr_source_map: primary
  vars_files:
    - disaster_recovery_vars.yml
    - passwords.yml
  roles:
    - oVirt.disaster-recovery

Corrected dr-rhv-failover.yml

- name: Failover RHV
  hosts: localhost 
  connection: local
  vars:
    dr_target_host: secondary
    dr_source_map: primary
  vars_files:

    - passwords.yml
  roles:
