Added protobuf changes for reservation refinement.
With reservation refinement, we now represent the reservation state in
`Resource.reservations` rather than with `Resource.role` and
`Resource.reservation`. We also keep track of the type of reservation,
and the role the reservation is for in the `Resource.ReservationInfo`.
This patch introduces these changes and explains the different formats
in detail.

>
> With the introduction of hierarchical roles, Mesos provides a mechanism to
> delegate resources down a hierarchy.
> To complement this, we'll introduce a mechanism to *refine* the reservations
> down the hierarchy.
> For example, given resources allocated to role {{foo}}, it can be further
> reserved for {{foo/bar}}.
> When the resources allocated to {{foo/bar}} is unreserved, it goes back to
> where it came from. In this case, back to role {{foo}}.
