Running remove-node.yml tasks for clean up cluster on Fedora CoreOS.
The task failed to restart network daemon (task name: "reset | Restart network").
Fedora CoreOS is essentially using NetworkManager, but this task returns network.

If crictl (and docker) binaries are deployed to the directories
that are not in standard PATH (e.g. /usr/local/bin), it is required
to specify full path to the binaries.

crio refuses to delete pods when cni is unavailable which is the
case e.g. using calico with kdd datastore. See:

https://github.com/cri-o/cri-o/issues/4084

Fix by deleting storage associated with containers. Stop and disable
crio service so switching container runtime can be done.

reset playbook fails and does not continue cleanup after for
example a host reboot with kubelet stopped/disabled

* change /etc/ssl/etcd to etcd_config_dir param

* add use etcd_events_data_dir param

* add remove_node_ip

* move remove_node_ip to remove etcd part

* fix: remove tail space

* fix: handle ubuntu: focal

When kube-router is used as cni, rules might be added to the mangle table
to support external IPs. Therefore, mangle table should be flushed during
reset as well.

* Fix python3-libselinux installation for RHEL/CentOS 8

In bootstrap-centos.yml we haven't gathered the facts,
so #5127 couldn't work

Minimum ansible version to run kubespray is 2.7.8,
so ansible_distribution_major_version is defined an there is no need to default it
