Integrate `conditions` API for all relevant API resources in IronCore

[balpert89]

Summary

The meta package in K8S apimachinery exposes a Condition struct which enriches status fields with information such as transitionTime, different fine-granular condition types and reasons why this condition has been set.

The controller-utils package offers utility functions around conditions.

Basic example

// either introduce our own condition type or leverage the apimachinery condition type
type ConditionWithTimestamps struct {
	Type               string
	Status             corev1.ConditionStatus
	LastUpdateTime     *metav1.Time
	LastTransitionTime *metav1.Time
	Reason             string
	Message            string
}

type MachineStatus struct {
	...
	Conditions []ConditionWithTimestamps
}

Naming is up for suggestions.

The potential resources ConditionsAPI to be integrated to

• Machine
• Volume

Motivation

The IronCore API should start actively leveraging this feature to enhance operational observability of API resources.
