There's 0.4.1 which has version constraints like version.NewConstraint(">= v1.23.0+k0s.2").Check(k0sVersion)

This is going to be annoying because either this or stdlib context needs to be imported with a name. Maybe something like apcontext?

This PR introduces a fully standalone logic in autopilot to follow different update channels.
The (upcoming) update server will host channels in this way:
latest: 1.28.0
stable/v1.27: 1.27.x (what ever is the latest in 1.27 series)
stable/v1.26: 1.26.x (what ever is the latest in 1.26 series)
unstable/v1.28: 1.28.0-beta.1 (what ever is the latest pre release in 1.28)
For each channel the update-server "protocol" is a simple yaml data:
```yaml
channel: latest
version: v5.6.7
downloadURLs:
- arch: amd64
os: linux
k0s: http://localhost/dist/k0s
k0sSha: deadbeef
airgapBundle: https://url.to.airgap/k0s-images-amd64.tgz
airgapSha: deadbeef
- arch: arm64
os: linux
k0s: http://localhost/dist/k0s
- arch: arm
os: linux
k0s: http://localhost/dist/k0s
```
Essentially this offers an easy way for users to either always follow the latest version or stay up-to-date with some specific minor version.
Each time k0s checks for possible updates it sends some general cluster details to the update server to allow the server also to make some decicions which update to push. Following data is sent in HTTP Headers:
```
K0S_StorageType: etcd/kine
K0S_ClusterID: uuid of kube-system NS
K0S_ControlPlaneNodesCount: 3
K0S_WorkerData: base64 encoded json of worker node arch, OS type, container runtime type
```
On top of the autopilot functionality there's a common component that will check if there's updates available and notifies cluster admin via Event. This checker does not perform any real updates, it's just a convenience way to inform admins there's new versions available. Neither does this component perform any checks if there is already a autopilot UpdateConfig in place.
