Klaus Ma commented on MESOS-3022:
---------------------------------
Scheduler version is necessary according to the following description; but we
did not need to build it from scratch, MESOS-1841 has a patch for master; we
can add scheduler's.
CC [~haosd...@gmail.com], [~marco-mesos] to align the solution.

The scheduler driver version could be used during troubleshooting to identify
frameworks that are using an old, potentially backwards incompatible, scheduler
driver (eg, a framework hasn't been restarted after a Mesos deploy, so it still
links against an old incompatible libmesos).

> The scheduler driver only exports the metrics below, but ideally it would
> export its version and a count of messages by message type.
