  1. Trim unneeded fields stored in informers to reduce memory footprint 

    Unused fields stored in informers can occupy significant memory usage.
The informer provides a transformer func to allow mutating the objects
before they are stored, via which we can trim unneeded fields.

In general, managedFields is never used for all types of objects. In
addition, we trim some unneeded fields from Pod objects given their
unused fields take the most considerable space.

It can reduce the memory usage of 1k simple Pod by approximately 5m.
