* fixes #866

* Make ocp-clientvm work with OSP cloud-provider

- create sample_vars_osp.yml
- create osp_default_vars.yml in the cloud_provider directory
- create infra-osp-dns role for creation and deletion
  Will create entries for every instances that has 'public_dns: true'
- cleanup infrastructure playbooks, move tasks into roles
- update ocp-clientvm version to 3.11.154

- don't update all packages

* ocp4-disconnected-osp-lab: Always add guid and env_type metadata
