[18/50] incubator-gobblin git commit: Don't start services if non is
needed
Don't start services if non is needed
When process isolation feature is enabled, there
may be no services
required to start in the worker process.
In this case, we will get a waring as below:
"Jan 23, 2018 10:43:50 AM

Fix:
Don't use serviceManager if no service is needed.
Testing:
Ran with the basic integration test and verified
the warning is gone is
the log.
Closes #2259 from HappyRay/do-not-start-services-
if-none-is-needed
