With this enhancement, the controller can be configured with `--watch-label-selector`, after which only objects with this label will be reconciled by the controller. This allows for horizontal scaling of the helm-controller, where each controller can be deployed multiple times with a unique label selector which is used as the sharding key. Note that if you want to ensure a `HelmChart` gets created for a specific source-controller instance, you have to provide the labels for this controller in `.spec.chart.metadata.labels` of the `HelmRelease`.
