* Use python3-libselinux on RHEL8/Centos8

* The fact ansible_facts.distribution_major_version is not present on older Ansible version.
Default it to 0 in when not present and use libselinux-python as package to get current
default behaviour.

Previous logic used calicoctl.sh create --skip-exists, which
allowed setting initial values, but not permitting changes.

* Added CRI-O support for ubuntu

* implemented feedback

* set crictl to fixed version

* Fix errors during rebasing

* Fix linting errors

Fix for Kubespray Issue #5059 (https://github.com/kubernetes-sigs/kubespray/issues/5059). There is a known issue with the 'fetch' module that will sometimes lead to it failing with a memory error. See ansible/ansible#11702 (https://github.com/ansible/ansible/issues/11702). I encountered this issue with the "Copy kubectl binary to ansible host" task in kubespray/roles/kubernetes/client/tasks/main.yml, and it caused my entire deployment to error out (see "Output of ansible run" above). Replacing 'fetch' with 'synchronize' fixes this issue.

Updated Openstack to terraform 0.12 (#5062)

* update openstack to terraform 0.12(.5)

* replace cluter.tf with cluster.tfvars

* update README.md to terraform 0.12

* update Openstack CI tests to use terraform 0.12

* specify terraform version in openstack README

* gitlab CI to copy cluster.tfvars in case of openstack provider

* The terraform/openstack dynamic inventory can read
tfstate v4 (generated by terraform 0.12) and convert them internally
ro v3 (as generated by terraform 0.11.x).

Additionally the script has been updated to Python 3.

According to their compatibility matrix[1] the 1.11.5 version seems to
be deprecated. This change updates the CentOS repository reference.
