----------------------------------------------------------------
I think the scheduler version does not be as a metric, because it is a static
value, and maybe we should provide another way to get the version for framework
if it is needed.
If we want to add version as a metric, then we need to add a new metric type
(for example, tag), the current metric types timer,counter and gauge do not
meet the requirement.
[~benjaminhindman] and [~vinodkone], any thoughts for this?

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

> "scheduler/event_queue_messages": 0,
> "system/cpus_total": 24,
> "system/load_15min": 0.49,
> "system/load_1min": 0.36,
> "system/load_5min": 0.46,

> 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).
> A count of messages by message type would help identify a problem w/ a
> specific feature, eg task reconciliation.
