MRPU support

[jaredkalmus]

This script will no longer work for the majority of customers on September 1st when Kenna roles out multiple roles per user functionality. "role" field will need to change to "roles", and role names will need to be passed as part of an array. I suggest creating a legacy version of the script for customers without MRPU, while updating the default script to use MRPU by default
