Personalized Greeting on Acceptance Emails

[BenGalewsky]

As an MDF Contributor I want to see my own name in the submission email so I have increased confidence it was correctly accepted

Description

MDF Connect 1.0 put the submitting user's first name as a greeting in the acceptance email. The first name is known in the Authorizer lambda but is not passed down to the submit lambda. It will need to be added to the JSON document placed in the Submit lambda's context and then put into the Flow input document.
