14749df6f3 Fix "netchecker-server" ClusterRole (#4730)
* Add sha256 hashes for calicoctl v3.6.1

Hashes are added to calicoctl_binary_checksums for both adm and arm platforms.

* Add rules for "network-checker.ext" resource to "netchecker-server" ClusterRole

So that it could access the resource after it is created.

fc072300ea Purge legacy cleanup tasks from older than 1 year (#4450)
We don't need to support upgrades from 2 year old installs,
just from the last major version.

Also changed most retried tasks to 1s delay instead of longer.

5f12b7aedf Remove kubedns and dnsmasq. Move dns_late phase after apps (#4406)
Both kubedns and dnsmasq modes are long not maintained.
We should run dns_late steps at the end because sshd
makes DNS lookups during Ansible run and has 2s timeouts
for each failed lookup trying to connect to coredns before
it is ready.

cache.

I believe this can usefull for more people.

c83bfc9df6 fix dns_prevent_single_point_failure variable (#3728)
comparison that happens during `TASK [kubernetes-apps/ansible : Kubernetes Apps | Lay Down CoreDNS Template]` where the `dns-autoscaler` template is deployed causes coredns to fail deployment.  The error is caused by the variable `dns_prevent_single_point_failure` where an integer is being compared with a string. The resulting error:

```bash
'>' not supported between instances of 'int' and 'str'
```

prevents successful deployment of CoreDNS.  

The change makes the comparison happen between integers and allows CoreDNS to succeed.
