On an opportunity page (opportunities -> select an opportunity), create a dropdown and button at the bottom of the page. The dropdown should be labeled with "add volunteer" and allow an admin user to select any volunteer that is not already in the table. When the user clicks the "add" button, there should be a new row added to the table.
