--------------------------------------

             Summary: Update allocator to handle multi-role frameworks.
                 Key: MESOS-6635
                 URL: https://issues.apache.org/jira/browse/MESOS-6635
             Project: Mesos
          Issue Type: Task
            Reporter: Benjamin Mahler


The allocator needs to be adjusted once we allow frameworks to have multiple roles:

(1) When adding a framework a framework, we need to store all of its roles and add it to multiple
role sorters.

(2) We will CHECK that the framework does not modify its roles when updating the framework
(much like we do for single-role frameworks).

(3) When performing an allocation, the allocator will set allocation_info.role. When recovering
resources, the allocator will unset allocation_info.role.

(4) The allocator will send AllocationInfo alongside offers that it sends to the master, so
that the master can easily augment {{Offer}} with allocation info.
