text: Title: Enhance netpol E2E tests connectivity information on startup 
  Body: <!-- Please only use this template for submitting enhancement requests -->
  
  **What would you like to be added**:
  
  Improve logs and connectivity debugging information on Netpol E2E tests suite bootstrap, so it will give us fine-grained info:
  https://github.com/kubernetes/kubernetes/blob/73d4c245ef870390b052a070134f7c4751744037/test/e2e/network/netpol/kubemanager.go#L253
  
  It can be a quick check-in of the health of the components, for example. 
  
  **Why is this needed**:
  
  This can help diagnostics failed infrastructure before starting the actual pod probing (which will fail),
