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](https://github.com/kubernetes/kubernetes/pull/82966)
