phase1 rocky failing due to missing default value for validate_services (undefined)

[Rafael Folco]

https://ci.centos.org/job/tripleo-quickstart-promote-rocky-rdo_trunk-minimal/116/consoleText

The conditional check 'validate_services|bool' failed. The error was: error while evaluating conditional (validate_services|bool): 'validate_services' is undefined

The error appears to have been in '/home/jenkins/workspace/tripleo-quickstart-promote-rocky-rdo_trunk-minimal/usr/local/share/ansible/roles/validate-services/tasks/containers.yaml': line 2, column 3, but may
be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:

---
- name: Do we have docker
  ^ here

fatal: [overcloud-novacompute-0]: FAILED! => {}
