   ### Requirement or improvement

   A canonical path to trigger auto-injection is to insert dedicated 
**annotations** to workloads and namespaces, then **`operator`** intercepts the 
provision of their pods, injecting agent relevant pieces into pod template. The 
result of injection might like below:
