Description
Would you like to work on this feature?
yes
What problem are you trying to solve?
While trying to implement a requirement to reconcile objects based on label existence on either the object of the objects Namespace, we faced with missing functionality. Passing label selector to the controller to establish watches on the resource is not possible in this scenario without duplicating cache content, or entirely ignoring label selectors in watch and storing all watched resources in memory.
In such case we need to perform label selector matching logic on the client side.
Describe the solution you'd like
#1482 or similar.
User can preserve the original LabelSelector for serialization/deserialization purposes.
A separate structure capable of converting From LabelSelector will allow to perform match operation on the resource or directly resource labels.
