Enable WireGuard on Calico CNI

[mariusv]

Calico CNI now has built in WireGuard and to enable it one needs to run calicoctl patch felixconfiguration default --type='merge' -p '{"spec":{"wireguardEnabled":true}}' wondering how hard will it be to have it in the kops cluster spec file as something like:

  networking:
    calico:
      wireguardEnabled: true

Hey @mariusv, this should be pretty easy. This would require a few changes:

1. add the new config option that will set FELIX_WIREGUARDENABLED = true in the manifest
2. install the wireguard package for the supported distros
3. test various scenarions
4. add docs

What happens if wireguard is enabled and the package is not installed?

Example on how to add a new option: #8076
Add a task to install the Wireguard package here:

kops/nodeup/pkg/model/networking/calico.go

Line 34 in 4af83f3
