feat(linker): get owner reference from creation snapshot first

[xuqingyun]

Description

• get owner reference from creation snapshot first to reduce apiserver request
• linker.Lookup is called when create link spans and also when create new object spans. for a new object, usually creation audti will fetch creation snapshot once and cache snapshot in local memory, it is expected that this will not lead to more request pressure to the caching storage
