WIP: Track allocation candidates to bound allocator.


Bugs: MESOS-3157
    https://issues.apache.org/jira/browse/MESOS-3157


Repository: mesos


Description
-------

- Triggered allocations dispatch allocate() only
  if there is no pending allocation in the queue.
- Allocation candidates are accumulated and only
  cleared when enqueued allocations are processed.
- Batched allocations are handled synchronously.
