🚀 Features

[USER]

• (#​236, @​MichaelSp)
• Domain metrics are now exposed via the Prometheus /metrics endpoint as metrics_operator_resource_count. DataSink is now optional: if no DataSink is configured, the operator continues to reconcile and records metrics to Prometheus only. (#​228, @​MichaelSp)
• Remove unused webhook related resources from helm chart + rbac is optional (#​227, @​AndresNico)

[BREAKING]

Defaulting behaviour of dataSinkRef was removed
The dataSinkRef previously defaulted to the "default" DataSink if not set. This default has been removed to allow metrics to run without any OTLP export. For new metrics, dataSinkRef must be set explicitly if OTLP export is desired:

spec:
  dataSinkRef:
    name: default

Existing metrics that relied on the default will continue to work, as the field was already persisted on their spec.
