The original PR set the recommended labels to:
app.kubernetes.io/name="postgresql" (utils.AppName, the cnpg
operator's identity)
app.kubernetes.io/version=<cluster PG major>
Per issue #545 the plugin's RBAC objects should advertise the
plugin's own identity:
app.kubernetes.io/name="barman-cloud-plugin"
app.kubernetes.io/version=<plugin semver>
Use metadata.Data.Version for the version value (always set,
never conditional on cluster image), drop the cnpg
GetPostgresqlMajorVersion lookup (irrelevant to plugin RBAC and
fragile against the cnpg PostgresImageName default), and extract
the plugin-local AppLabelValue and ManagedByLabelValue constants
so test and production share a single source of truth. The
labels_test.go helper now also asserts the version's value, not
just the key.
Document on metadata.ClusterLabelName that it's a discovery
contract for objectstore_controller.go (which selects on the
key), so the dual-labeling scheme (the legacy cluster label
alongside the K8s recommended labels) is explicit and the
legacy key cannot be silently removed by a later cleanup.
