> Add Resource.AllocationInfo in Offer to indicate a single role per offer.

> Key: MESOS-6634
> URL: https://issues.apache.org/jira/browse/MESOS-6634
> Project: Mesos
> Issue Type: Task
> Components: framework api
> Reporter: Benjamin Mahler
> Assignee: Jay Guo
>
> With multi-role framework support, we need to ensure that the framework can
> determine which resources are allocated to which roles. Since we'd like to
> preserve the offer semantics between a single multi-tenant scheduler and
> multiple single-tenant schedulers, we would like to ensure that an offer only
> contains resources allocated to a single role:
> {code}
> message Offer {
> required OfferID id = 1;
> ...
> required AgentID agent_id = 3;
> ...
> repeated Resource resources = 5;
> ...
> // An offer represent resources allocated to *one* of the
> // roles managed by the scheduler. (Therefore, each
> // `Offer.resources[i].allocation_info` will match the
> // top level `Offer.allocation_info`).
> optional Resource.AllocationInfo allocation_info = 10;
> }
> {code}
> The assumption is that this will make it easier for schedulers to manage
> offers, since each offer is made to a single tenant.
