Release notes for version 0.19.0

Release date: 2024-02-09

• Do not store original labels in vmagent's memory by default. This reduces memory usage of vmagent but makes vmagent's debugging UI less informative. See this docs for details on relabeling debug.
• Update dependencies: kube-state-metrics -> 5.16.0, prometheus-node-exporter -> 4.27.0, grafana -> 7.3.0.
• Update victoriametrics CRD resources yaml.
• Update builtin dashboards and rules.
