> Currently, we do not set {{ReservationInfo}} for static reservations. Moreover, we suggest
that frameworks determine if a resource offer contains dynamically reserved resources by checking
whether the {{ReservationInfo}} field is set. This means that if we want to add new reservation-specific
information (e.g., labels), we can't put those fields into {{ReservationInfo}} if we want
them to be supported by static reservations.
> Proposed plan:
> * Continue to add reservation-specific information to {{ReservationInfo}}, which means
it won't be supported for static reservations
> * Set {{ReservationInfo}} for both static and dynamic reservations
> * Introduce a new enum to describe the type of the reservation, and encourage frameworks
to use this field to check for whether a resource offer has a reservation.
> The tricky part is the backward compatibility story.
