release-0.23.4

Changed

• Allow adding pod labels in Helm chart by @bruno-s-coelho in #1369. Closes #1356
• The default service type has been changed from LoadBalancer to ClusterIP
• Cluster restart rules were fixed for some structured settings like 'logger/*'. Now changing of those would not cause a restart of pods.
• Operator does not fail if ClickHouserKeeperInstallation resource type is missing in k8s
• Added 'clickhouse_operator_chi_reconciles_aborted' operator metric

NOTE: There was a lot of internal refactoring related to Keeper code, but no functional changes yet. The Keeper configuration functionality will be improved in the next major release.
