text: Title: [UX] Additional message from OCI even though not enabled
  Body: <!-- Describe the bug report / feature request here -->
  
  I am getting the following message while `sky launch -c test` with `pip install -e .[all]` and no OCI credentials
  
  ```
  INFO:oci.circuit_breaker:Default Auth client Circuit breaker strategy enabled
  ```
  
  We should get rid of this.
