   oc get pods:
   examplebranchoperatorbranching.405a5270d25b4783a219c48e2f9fc267   0/1     Init:1/2   0          101s
   
   worker pods are starting very slow.
   investigated the logs, the k8s init container takes a lot of time to start:

   How to make it faster?
   
   **How to reproduce it**:
   
   Use Airflow with kubernetes executor and check worker pod starting time.
