Provide more fine grained transnational control capabilities at Output to RDMBS time.

Hello gurus - 

Pretty much every coding framework supports this.  If we really want Alteryx to embrace no-code, we've got to have some ability to control commit / rollbacks across transactions.  As it stands currently, it is pretty easy to write out parent records, fail to be able to write out children, and wind up with a database state that makes the end users very sad.  

Thanks!

This could also help with error debugging as things like timeouts or operations at various transaction states can affect performance and/or errors.
