extend support for handling more events from libvirt daemon

[lukas016]

Summary

current issue #177 integrate only basic event handler for lifecycle events. But libvirt daemon support more kind of events: https://pkg.go.dev/github.com/digitalocean/go-libvirt#DomainEventID

Minimally we will need to support these events: DomainEventIDDeviceRemoved, DomainEventIDDeviceAdded

But i prefer create general and easy extendable solution for handle all events which can be configurable with arguments.
How it will specific work, it will depend on implementation of issue.

Basic example

--machine-controller-libvirt-events=deviceRemoved,deviceAdded

or

--machine-controller-libvirt-events-exclude=metadataChange

Tasks

• create design
• present design
• implement approved design

Motivation

Handling more libvirt daemon events easier.
