[Sprint: 40] XD-2430 Adding a Sqoop tasklet and Sqoop batch job

- ported the Sqoop job POC over and added a Sqoop tasklet to handle capturing logs to be stored in the step execution context

- added an AbstractProcessBuilderTasklet that provides support for running this type of jobs in a separate process. This could be used by the Spark tasklet as well.
I guess you're right.  Just seemed like an odd thing to have a hibernate dependency here given that we don't import hibernate anywhere else in XD (a search for org.hibernate turns up nothing beyond these validator annotations in the project).
