What this PR does / why we need it?:

  • Optimizes resource sharing (LTPA/Password Encryption keys) by caching the DecisionTree into a global *sync.Map.
  • Enables MaxConcurrentReconciles by making the operator config map and resource sharing CR instances threadsafe.

Does this PR introduce a user-facing change?

  • User guide
  • CHANGELOG.md

Which issue(s) this PR fixes:
