* [calico] make vxlan encapsulation the default
* don't enable ipip encapsulation by default
* set calico_network_backend by default to vxlan
* update sample inventory and documentation
* [CI] pin default calico parameters for upgrade tests to ensure proper upgrade
* [CI] improve netchecker connectivity testing
* [CI] show logs for tests
* [calico] tweak task name
* [CI] Don't run the provisioner from vagrant since we run it in testcases_run.sh
* [CI] move kube-router tests to vagrant to avoid network connectivity issues during netchecker check
* service proxy mode still fails connectivity tests so keeping it manual mode
* [kube-router] account for containerd use-case
* Docs: update CONTRIBUTING.md
* Docs: clean up outdated roadmap and point to github issues instead
* Docs: update note on kubelet_cgroup_driver
* Docs: update kata containers docs with note about cgroup driver
* Docs: note about CI specific overrides
* Fix invalid link to Ansible documentation
* Fix invalid link to mitogen doc page
* Fix invalid link to calico doc page
* Fix all invalid links to doc pages
* Fedora and RHEL use etc_t and the convention is <type_name>_t
* Docs: specify all values for preinstall_selinux_state
* CI: Add Fedora 34 with SELinux in enforcing mode
* rename ansible groups to use _ instead of -
k8s-cluster -> k8s_cluster
k8s-node -> k8s_node
calico-rr -> calico_rr
no-floating -> no_floating
Note: kube-node,k8s-cluster groups in upgrade CI
need clean-up after v2.16 is tagged
* ensure old groups are mapped to the new ones
* Add documentation for audit webhook variables
* Enclose the value of audit_webhook_server_url in a codeblock
* Add default value for audit_webhook_batch_max_wait
This replaces kube-master with kube_control_plane because of [1]:
The Kubernetes project is moving away from wording that is
considered offensive. A new working group WG Naming was created
to track this work, and the word "master" was declared as offensive.
A proposal was formalized for replacing the word "master" with
"control plane". This means it should be removed from source code,
documentation, and user-facing configuration from Kubernetes and
its sub-projects.
NOTE: The reason why this changes it to kube_control_plane not
kube-control-plane is for valid group names on ansible.

* Fix incorrect assertion comparison for kube_network_node_prefix
* Ignore assertion comparison for kube_network_node_prefix when using calico
* Adding more var docs description for kube_network_node_prefix
* Fixing trailing whitespaces
* Introduce kubelet_config_extra_args and kubelet_node_config_extra_args to pass params to kubelet via YAML config
* kubelet_config_extra_args is not the alternative
