Sent task (health) check updates over the operator streaming API.
With this patch subscribers to the master operator streaming API
start receiving task health (check) updates. This allows subscribers
to maintain more accurate view of the cluster's state, closer to
what the traditional `state.json` endpoint offers.

> Master streaming API does not send (health) check updates for tasks.
> --------------------------------------------------------------------
>
> Key: MESOS-8942
> URL: https://issues.apache.org/jira/browse/MESOS-8942
> Project: Mesos
> Issue Type: Task
> Components: HTTP API
> Affects Versions: 1.4.1, 1.5.0, 1.6.0
> Reporter: Alexander Rukletsov
> Assignee: Alexander Rukletsov
> Priority: Major
> Labels: api, mesosphere, streaming-api
>
> Currently, Master API subscribers get task status updates when task state
> changes (the actual logic is [slightly more
> complex|https://github.com/apache/mesos/blob/d7d7cfbc3e5609fc9a4e8de8203a6ecb11afeac7/src/master/master.cpp#L10794-L10841]).
> We use task status updates to deliver health and check information to
> schedulers, in which case task state does not change. Hence these updates are
> filtered out and the subscribers do not get any task health updates.
> Here is a test that confirms the described behaviour:
