   Dear Gobblin maintainers,
   
   Please accept this PR. I understand that it will not be reviewed until I 
have checked off all the steps below!
   
   
   ### JIRA
   - [ ] My PR addresses the following [Gobblin 
JIRA](https://issues.apache.org/jira/browse/GOBBLIN/) issues and references 
them in the PR title. For example, "[GOBBLIN-1721] My Gobblin PR"
       - https://issues.apache.org/jira/browse/GOBBLIN-1721
   
   
   ### Description
   - [ ] Here are some details about my PR, including screenshots (if 
applicable):
   Currently when we receive a job restart(handleUpdateJobConfigArrival), 
GobblinHelixJobLauncher will firstly call  helixTaskDriver.waitToStop to stop 
the workflow, then initiate the new one. We observe the behavior of Helix 
taking exceptionally long to stop the workflow, making the job state staying in 
STOPPING status. This will make waitToStop timeout and throw exception all the 
time, making the new flow never be able to launch.
   
   We can utilize Delete API in this case since our job is stateless for Helix, 
to avoid job hanging.
   
   ### Tests
   - [ ] My PR adds the following unit tests __OR__ does not need testing for 
this extremely good reason:
   Tested in the cluster.
   
   ### Commits
   - [ ] My commits all reference JIRA issues in their subject lines, and I 
have squashed multiple commits if they address the same issue. In addition, my 
commits follow the guidelines from "[How to write a good git commit 
message](http://chris.beams.io/posts/git-commit/)":
