  1. salt: Use cluster_version in upgrade apiserver orchestrate 

    Instead of relying on a pillar key `orchestrate.dest_version` in
orchestrate.apiserver salt states use the `metalk8s.cluster_version` key
from the pillar (which is the version in the kube-system namespace

  2. salt,script: Move upgrade logic from orchestrate to script 

    Since we use a script and we rely on salt-master running in a static pod
on the bootstrap node we need to move some logic outside of the salt
orchestrate to the script so that salt-master restart can be handled
properly (and not brutaly interupt a salt orchestrate execution.
- Etcd cluster upgrade is now part of the upgrade script
- All APIServers upgrade is now part of the uppgrade script
- Upgrade bootstrap engines (kubelet + containerd) locally
- Then call the orchestrate to upgrade all nodes one by one
This commit also add a warning in the upgrade orchestrate so that we now
that this orchestrate is only a part of the upgrade process

Fixes: #2908

  3. salt: Upgrade orchestrate small improvement 

    Do no longer provide `orchestrate.dest_version` pillar key to
`upgrade.precheck` as it do not use it, update `require_in` so that we
no longer run `Deploy Kubernetes service config objects` if one node
upgrade failed
