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)

* dead link

* triggger ci

* Update containerd package to 1.2.13-3.2.el7

* Update Fedora containerd package versions.

* Update Redhat containerd stable and edge packages.

Since MetalLB v0.8[1], metallb:speaker has started publishing an event
nodeAssigned on k8s resource.
To support MetalLB v0.8+, this allows metallb:speaker to create events.

Modify the populate no_proxy task to use a combine rather than relying on the hash_behaviour setting to be set to merge rather than replace (#6112)

Since weave 2.5.1, `NoExecute` taint effect is no more supported,
this changes the daemonset tolerations to change this behavior.

Also remove the toleration key `CriticalAddonsOnly` not required anymore.

If running MetalLB v0.7.3 on k8s v1.18.2, metallb pods output the
following parsing error of v1.ServiceList:

  $ kubectl logs controller-dbb46cf84-fw8h8 -n metallb-system
  {
    "caller":"reflector.go:205",
    "level":"error",
    "msg":"go.universe.tf/metallb/internal/k8s/k8s.go:231:
      Failed to list *v1.Service: v1.ServiceList:

        v1.ObjectMeta: readObjectFieldAsBytes:
        expect : after object field, parsing 1605

Then an external IP address is never allocated to the Service of
LoadBalancer type.
By updating MetalLB version to the latest v0.9[1] today, this issue
can be solved.

* fix(handlers,kubelet): setting right notify task name

* update documentation to add and remove nodes

* add information about parameters to change when adding multiple etcd nodes

* add information about reset_nodes

* add documentation about adding existing nodes to ectd masters.

* Add additional network configuration options to external Openstack CCM (#6083)

* Change the default version of external openstack cloud controller image to v1.18.1 since there was an issue in v1.18.0 where some IPs of the private network were ignored

* Change Network section in external-openstack-cloud-config.j2 to Networking

* Add networking customization information in the openstack documentation

This updates MetalLB README as following
- Remove unnecessary markdown to read it easily on github
- Make words consistency (kubernetes, loadbalancer)
- Add change-required option

Due to lack of requirements installation on Azure README, the error
can happen:

 "The ipaddr filter requires python's netaddr be installed on the
  ansible controller"

It is nice to add the installation for Azure users.
