Review request for mesos and Jiang Yan Xu.


Bugs: MESOS-4431
    https://issues.apache.org/jira/browse/MESOS-4431


Repository: mesos


Description (updated)
-------

Each shared resource is accouted via its share count. This count is
updated based on the resource operations (such as add and subtract)
in various scenarios such as task launch and terminate at multiple
modules such as master, allocator, sorter, etc.
Only allow DESTROY if no task is using the volume, or has not been
offered to any framework.
Since shared resources are available to multiple frameworks of the
same role simultaneously, we normalize it with a weight equivalent
to the number of frameworks to which this shared resource has been
allocated to in the sorter.
