do we need to save the entire data/field contents here ?
can the map look something like

map[string]string{ "<ns>/<name>/<field>/<valueRefKind>/<name>": <ns>, }

this would allow us to

save space

build a map before using it in buildTrafficFeatures and each new feature can enhance this

cross ns references are a security concern, so will require test coverage for the non happy paths

@arkodg if the exact same local object ref exists in response overrides of parent and route policies, what should be the behavior? Check the first case in the tests I just added.

Check same LocalObjectRef different match criteria test where only one local object ref will remain if entire ResponseOverride is not used as key.

save space

also this is not persisted memory, will be used only while building the IR
