Description

Thanks to the resource reservation primitives, frameworks can reserve resources. These reservations are per role, which means multiple frameworks can share reservations. This can get very hairy, as multiple reservations can occur on each agent.

It would be nice to be able to optionally, uniquely identify reservations by ID, much like persistent volumes are today. This could be done by adding a new protobuf field, such as Resource.ReservationInfo.id, that if set upon reservation time, would come back when the reservation is advertised.
