Review Request 68662: Avoided double copying of outgoing messages in the master.

Review request for mesos, Gastón Kleiman, Gilbert Song, and Greg Mann.


Bugs: MESOS-9213
    https://issues.apache.org/jira/browse/MESOS-9213


Repository: mesos


Description
-------

When framework metrics were introduced, there was an evolve + devolve
conversion occuring in order to map old style messages to the new
`scheduler::Event::Type`. This results in copying all outgoing
messages twice.

This patch avoids the copying by adding overloads for the old style
messages.

Chatted with Gastón offline, we weren't able to take this out because it's a run-time invariant. We could remove this if we update the master code to avoid calling it by checking its invariants and upgrading into an Event.

    This kind message is not sent to v0 schedulers, so we should take it out.

    Nit: this comment sounds a bit awkward to me? Maybe something like:
    
    "Overloads to convert old, unversioned scheduler messages into their event counterparts."
