Review request for mesos, Benjamin Mahler and Meng Zhu.


Addressed BenM's comments.

Bugs: MESOS-9616

Repository: mesos


Currently if a framework accepts an offer to perform pipelined
operations, e.g., reserving resource, without a final consumer, the
converted resources will be implicitly refused. This is an undesired
behavior as the framework might want to reserve one resource first but
launch a task later in the next allocation cycle. This patch fixes this

But, if the framework accepts an offers with multiple operations that
cancel out each other, the resources consumed by these operations are
still considered unused and will be refused.
