Sync contacts from Discovery participants to Salesforce contacts

Maintaining a single source of truth for interview participants.

Currently the Salesforce integration supports a 1-way sync of Contacts from Salesforce to Discovery participants. Where participants are added in Discovery, for example where they join an interview, they must be manually added as contacts in Salesforce.

Having a 2-way sync would reduce manual work in keeping a central participant list up to date between Aha! and Salesforce.
