Add ServiceOperations class to aid working with Services
--------------------------------------------------------

                 Key: MAPREDUCE-3970
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-3970
             Project: Hadoop Map/Reduce
          Issue Type: Sub-task
          Components: mrv2
    Affects Versions: 0.23.1, 0.24.0
            Reporter: Steve Loughran
            Assignee: Steve Loughran




Add Helper methods to move things through lifecycles. init->start is common, stop-if-service!=null
another. Some static methods can execute these, and even call stop() if init() raises an exception.
These could go into a class ServiceOps in the same package. These can be used by those services
that wrap other services, and help manage more robust shutdowns.
