Review request for mesos and Ben Mahler.


Updated with bmahler's review comments.

Bugs: MESOS-3157

Repository: mesos


Normally, the mesos-master performs allocation cycles in response
to protocol messages and cluster events. This ties the cost of
allocation to the amount of churn in the environment, which can led
to unpredictable performance. Add an option to disable this, meaning
that allocations are only every performed by the batch interval
task. This makes resource allocation a fixed cost, independent of
the amount of environmental churn.
