   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
   - [x] 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-XXX] My Gobblin PR"
       - https://issues.apache.org/jira/browse/GOBBLIN-1653
   
   
   ### Description
   - [x] Here are some details about my PR, including screenshots (if 
applicable):
   
   Gobblin uses jobName to create folder paths for temporary work folders. In 
GaaS, the jobName is composed of the flowGroup, flowName, edge ID, and some 
hash. This combination can exceed the maximum folder component length if the 
flowName and flowGroup approaches their maximums (128 characters). 
   
   Instead of enforcing a shorter flowGroup/flowName (which would require many 
db migrations), we should shorten the jobName sent to Gobblin as it's only used 
for temporary file storage. We would set the jobName as <flowGroup> + <hash> 
where hash is computed from the input path of the dataset
   
   ### Tests
   - [x] My PR adds the following unit tests __OR__ does not need testing for 
this extremely good reason:
   
   
   ### Commits
   - [x] 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/)":
       1. Subject is separated from body by a blank line
       2. Subject is limited to 50 characters
       3. Subject does not end with a period
       4. Subject uses the imperative mood ("add", not "adding")
       5. Body wraps at 72 characters
       6. Body explains "what" and "why", not "how"
