> h3. Goal
> This is the first step to supporting dynamic reservations. The goal of this task is to enable a framework to reply to a resource offer with *Reserve* and *Unreserve* offer operations as defined by {{Offer::Operation}} in {{mesos.proto}}.
> h3. Overview
> It's divided into a few subtasks so that it's clear what the small chunks to be addressed are. In summary, we need to introduce the {{Resource::ReservationInfo}} protobuf message to encapsulate the reservation information, enable the C++ {{Resources}} class to handle it then enable the master to handle reservation operations.
> h3. Expected Outcome
> * The framework will be able to send back reservation operations to (un)reserve resources.
> * The reservations are kept only in the master since we don't send the {{CheckpointResources}} message to checkpoint the reservations on the slave yet.
> * The reservations are considered to be reserved for the framework's role.
