Description

This ticket refers to a milestone of SINGA-30.

Currently, we only support internal zookeeper service, which will be stopped and cleaned up for each singa job. That is because a job crash may leave zookeeper in an invalid state and affect future jobs.

To support external zookeeper, we should not stop the service each time. Instead, we need a tool to clean singa sub-folder in zookeeper.
