> Currently submitReservation returns a ReservationId if sucessful. This JIRA propose adding
a getNewReservation in ApplicationClientProtocol for the following reasons:
>   * Prevent zombie reservations in the face of client and/or network failures post submitReservation
>   * Align reservation submission with application submission
