CentOS 8 CI (#5842) 
* requirements.txt: Bump versions

Ansible 2.8+ allow ansible_python_interpreter autodetection

Signed-off-by: Etienne Champetier <champetier.etienne@gmail.com>

* tests: do not force ansible_python_interpreter

we do not expect people to set ansible_python_interpreter, so we should not set it in the CI

RHEL / CentOS 8

RHEL / CentOS 8 ships only with iptables-nft (ie without iptables-legacy) The only tested configuration for now is using Calico CNI You need to use K8S 1.17+ and to add calico_iptables_backend: "NFT" to your configuration

If you have containers that are using iptables in the host network namespace (hostNetwork=true), you need to ensure they are using iptables-nft. An exemple how k8s do the autodetection can be found in this PR
