[Core] New Filter: LabelSelector

[fjogeleit]

Currently it's possible to route resources to targets / channels based on namespace, source, policy and priorities.

For most cases this works fine but there are situations where a more fine grained / flexibel approach is needed. To achieve this I would like to add an labelSelector filter to route a result based on the labels of the related resource.

Requirements:

• Read permissions for the associated resources. (Resource labels are not part of the PolicyReport and must be fetched separately).

Any chance of this getting picked up & implemented? I'd really like to not have to explicitly list namespaces for channel filters & instead just use a label selector for the group of namespaces.

Hey, this relates to filter based on resource / report labels.

Routing via NS labels is available in the current alpha release of Policy Reporter v3.

See #382 for details.
