Pull request overview

This PR updates the Kubernetes Operations Helm chart to (1) enrich selected Kubernetes health alert expressions with optional kube-state-metrics labels and (2) remove legacy Plutono dashboards/templating while keeping Perses dashboards as the supported path.

Changes:

• Add optional prometheusRules.kubeLabels configuration and Helm helpers to join kube_pod_labels / kube_deployment_labels into specific alert expressions.
• Remove Plutono dashboard JSONs and the Plutono dashboard ConfigMap template; retain Perses dashboard selectors/config.
• Bump chart and plugin definition versions to align with the updated bundle.

charts/kubernetes-operations/plugindefinition.yaml:24

• spec.options still references Plutono and outdated values keys (prometheusRules.ruleSelector, dashboards.dashboardSelector). This no longer matches values.yaml (now prometheusRules.ruleSelectors and dashboards.persesSelectors) and conflicts with the Plutono sunset in this PR. Update the option names/descriptions (and consider exposing prometheusRules.kubeLabels too).

charts/kubernetes-operations/plugindefinition.yaml:24

• The PluginDefinition options still references Plutono and an outdated values key (prometheusRules.ruleSelector / dashboards.dashboardSelector). Since the chart has moved to Perses dashboards and uses prometheusRules.ruleSelectors + dashboards.persesSelectors, the current option names/descriptions will misconfigure the chart when set via Greenhouse. Update the option names/descriptions, and consider exposing the newly added prometheusRules.kubeLabels value here as well.
