Update Kubernetes, controller-runtime and Helm 
This commit updates Kubernetes to v1.27, controller-runtime to
v0.15, and Helm to v3.12.

It deals with various breaking changes in controller-runtime, as
documented in the release notes:
https://github.com/kubernetes-sigs/controller-runtime/releases/tag/v0.15.0

In short:

- `Watches` now use a `client.Object` instead of a `source.Kind`.
- `handler.MapFunc` signature accepts a Go context, which is used to
  log any errors, instead of silently ignoring them and/or panicking.
- Max concurrent reconciles is configured on the manager, instead of
  configuring them per reconciler instance.
- Various manager configuration options have been moved to new
  structures and/or fields.

In addition to this, all other dependencies which had updates
available are updated to their latest versions as well.

helm-controller

CII Best Practices e2e report license release

The helm-controller is a Kubernetes operator, allowing one to declaratively manage Helm chart releases. It is part of a composable GitOps toolkit and depends on source-controller to acquire the Helm charts from Helm repositories.

The desired state of a Helm release is described through a Kubernetes Custom Resource named HelmRelease. Based on the creation, mutation or removal of a HelmRelease resource in the cluster, Helm actions are performed by the operator.

overview

Features

  • Watches for HelmRelease objects and generates HelmChart objects
  • Supports HelmChart artifacts produced from HelmRepository, GitRepository and Bucket sources
  • Fetches artifacts produced by source-controller from HelmChart objects
  • Watches HelmChart objects for revision changes (including semver ranges for charts from HelmRepository sources)
  • Performs automated Helm actions, including Helm tests, rollbacks and uninstalls
  • Offers extensive configuration options for automated remediation (rollback, uninstall, retry) on failed Helm install, upgrade or test actions
  • Runs Helm install/upgrade in a specific order, taking into account the depends-on relationship defined in a set of HelmRelease objects
  • Reports Helm release statuses (alerting provided by notification-controller)
  • Built-in Kustomize compatible Helm post renderer, providing support for strategic merge, JSON 6902 and images patches
