This PR adds the basic functionality to add a rolling update support for nodes in a cluster to ProxLB.
If activated, nodes will:
Check if update for itself is available
Integrate the updates
Check if a reboot is required
Add self to ignore_nodes list
Rebalance the cluster (move workloads away from self)
Reboot
This also brings up the new proxlb-additions package, which adds the missing options to the Proxmox API. This packages will be required. If this option is activated but the package is missing, ProxLB will throw an error guiding you to install the required package.
