From 4.0.0, kubernetes-incubator/client-python uses multiprocessing
libaray to send request to k8s cluster, which is not supported by
eventlet. This patch introduced the following changes to fix the issue:
- Use cotyledon for engine service rather than oslo.service
- Update global requirments
- Provide separate scripts for api and engine service
