> Currently an {{Operation}} only contains a {{FrameworkID}} of originating frameworks, but e.g., not the full {{FrameworkInfo}}. This is problematic in master failover scenarios where a master might learn about an operation triggered by a framework unknown to it. The way the master implementation is structured, we would like to create tracking structures for that framework (e.g., to sync with the allocator down the line), but cannot do so since we can only learn this information when either the framework reregisters, or an agent running tasks of that framework reconciles with the master. We also cannot use conjured uo dummy information until we  learn the true {{FrameworkInfo}} since some required fields in {{FrameworkInfo}} (namely {{FrameworkInfo.user}}) cannot be updated, see MESOS-703.
> We should introduce a channel for agents to learn the full {{FrameworkInfo}} for all frameworks executing operations on its resources. For simplicity and symmetry with {{RunTaskMessage}} it seems that adding an explicit {{FrameworkInfo}} field to {{Operation}} would do the job (e.g., allow atomic information transfer when operations are sent to the agent or on reconciliation with newly elected masters.
