When using kubeadm managed etcd, configuring an etcd group can now
be skipped.

* calico: add constant calico_min_version_required

and verify current deployed version against it.

* calico: remove upgrade support with data migration

The tool was used pre v3.0.0 and is no longer needed.

* calico: remove old version support from tasks

* calico: remove old ver support from policy ctrl

* calico: remove old ver support from node

* canal: remove old ver support

* remove unused calicoctl download checksums

calico_min_version_required is the oldest version that can be installed
Older versions can be removed.

* Added ability to set calico vxlan vni and port. defaults to calico's documented defaults.

* Check if calico_network_backend is defined prior to checking value

* Removed calico hidden defaults for vxlan port and vni

* Fixed FELIX_VXLANVNI typo

* add FELIX_DEVICEROUTESOURCEADDRESS calico option

* add calico_use_default_route_src_ipaddr option 

add calico_use_default_route_src_ipaddr option to use FELIX_DEVICEROUTESOURCEADDRESS calico option

* Update k8s-net-calico.yml

* Update calico_veth_mtu to FELIX_IPINIP variable

calico_veth_mtu is specified in the configuration, but since it only works for wireguard, modify it to work for IP-in-IP users.

* Update template with more cleaner expression

flannel, ovn and multus network plugins did not support all taint keys. This
update changes the tolerations to support them all.

According to the documentation:

```
There are two special cases: An empty key with operator Exists matches all keys,
values and effects which means this will tolerate everything. An empty effect matches
all effects with key key.
```

Usage of the empty `key` and `effect` ensures the network plugin daemonset will
be deployed on every nodes (ex: in case of custom taints, or NoExecute effect)

disable bird-check flag for probes of calico-node pods when calico_network_backend is not 'bird'. (#6217)

* Support configuring the insert mode

Defaults to the upstream default https://docs.projectcalico.org/v3.9/reference/felix/configuration

so nothing should change for existing deployments.

This allows coexistence with other firewall management technologies.

* Add a note to the sample config

Adds `calico_iptables_lock_timeout_secs` variable to calico DS yaml.

I've tested this update by deploying a containerd / etcd cluster on top CentOS7,
MetalLB + NGINX Ingress. Upgrade using upgrade-cluster.yml
