Volunteer Photo Upload API

The "Login" endpoint (/api/volunteer/login - with method: POST) requires posting a json object with Id and Email Properties.

The "Update" endpoint (/api/volunteer/update - with method: POST) requires posting a json object with Id, FirstName, Lastname, Email and PhotoName properties (only the PhotoName is actually updated in the DB. Id and Email are mandatory or the photo info won't be saved).
