<!-- Feature requests are unlikely to make progress as an issue. Instead, please suggest enhancements by engaging with SIGs on slack and mailing lists. A proposal that works through the design along with the implications of the change can be opened as a KEP: https://git.k8s.io/enhancements/keps#kubernetes-enhancement-proposals-keps --> #### What would you like to be added: To clean up, we need to eliminate csiplugin-connector related codes. #### Why is this needed: csiplugin-connector codes no longer needs since we containerized efc & mount-helper codes. @DahuK
