Configure yamllint to be compatible with ansible-lint

Current version of ansible-list pre-commit hook required changes in the
ansible-freeipa yamllint configuration and these changes triggered
issues in the current playbooks on roles and tests.

This patch adds the required changes to yaml lint configuration and
fixes the affected playbooks.
