Will it always get OPERATION_UNREACHABLE? If not, then that would be cnofusing.

Continuing this discussion on Slack: https://mesos.slack.com/archives/C8NN4M0CT/p1549066656027000

Yep, I intended not to update the operation status in this patch. The JIRA issue is purely
for sending updates to frameworks, and I intend to address all of the operation state updates
as part of https://issues.apache.org/jira/browse/MESOS-9546 since that involves more significant
code changes.
