Review Comment:
Should we add flowExecutionId before calculating hash?

> Gobblin-as-a-Service creates jobnames using flowgroups flownames, edges, and
> jobnames from the template. However, this tends to create a very long string
> which then causes issues in Gobblin job when creating files that use the
> jobname to create working directories or state stores. Although there has
> been previous code that shortens job name lengths, we want to further
> increase this by being more aggressive with the maximum length of the jobname
> to reduce the odds of exceeding 255 chars (max length of HDFS component)
