Issue MESOS-5609: Put initial scaffolding in place for implementing SUBSCRIBE call on v1 Master API.
As discussed on MESOS-5498, this ticket is for tracking work to put the initial scaffolding in place for streaming task status update events to a client that has subscribed to the {{api/v1}} Operator API endpoint. Other events/support for snapshots would be done as part of MESOS-5498.
