Key personnel multi pi

Rather large change set that moves Multi-pi from a property on the person to a real role qualified by sponsor hierarchy name.

This work should also involve converting existing parameters that were used to tweak proposal roles in the past and move implementors existing values into this table. This will likely involve some external tool that can access both databases at the same time to be run during the database upgrade. Hopefully someone has some ideas on how to handle this?

A new maintenance document should also be created to manage the key person role table. Will we do this in KRAD or KNS?
