             Summary: Improve scheduler demand primitives
                 Key: MESOS-7789
                 URL: https://issues.apache.org/jira/browse/MESOS-7789
             Project: Mesos
          Issue Type: Epic
            Reporter: Benjamin Hindman


A scheduler can tell Mesos about it's demands via requests (not implemented), 
decline with filters, and suppress. We could improve this to make it easier for 
schedulers to just get the resources they care about as well as reduce the 
amount of traffic between the master and schedulers.

Some ideas:

* Implement requests.
* Introduce suppress + filters (i.e., suppress all resources that would get 
declined by the specified filter).
* Introduce a _limit_ that specifies the total amount of resources that I'll 
ever need allocated.
