> With support for multi-role frameworks, offers contain allocation info (currently just the role that the offer is being made to).
> In theory, schedulers could perform offer operations across multiple roles, so long as the tasks, executors, and reservations individually don't mix roles. However, there doesn't seem to be a clear reason to allow this. So, we will validate against combining offers from multiple roles. This also makes it semantically consistent with single-role frameworks (since they do not do this either).
