--------------------------------

             Summary: Starting maintenance needs to deactivate agents and kill 
tasks.
                 Key: MESOS-3265
                 URL: https://issues.apache.org/jira/browse/MESOS-3265
             Project: Mesos
          Issue Type: Task
          Components: master, slave
            Reporter: Joseph Wu
            Assignee: Joseph Wu


After using the {{/maintenance/start}} endpoint to begin maintenance on a 
machine, agents running on said machine should:
* Be deactivated such that no offers are sent from that agent.  (Investigate if 
{{Master::deactivate(Slave*)}} can be used or modified for this purpose.)
* Kill all tasks still running on the agent (See MESOS-1475).
* Prevent other agents on that machine from registering or sending out offers.  
This will likely involve some modifications to {{Master::register}} and 
{{Master::reregister}}.
