---------------------------------------
[~vinodkone], I have a problem for this ticket, if master is disabled for
oversubscription, then are all slaves to be disabled to report the revocable
resources in the same time?
IMHO：
1. Slaves as the resource providers, they should can decide whether enable or
disable oversubscription;
2. Frameworks as the resource consumers, they should can decide whether accept
or reject the revocable offers;
We can imagine that if slave can provide revocable resource and framework also
accept the revocable offer, then Mesos master should always allocate the
revocable resource. Mesos master/allocator is only the resource allocator, it
should not guard this.
> Add master flag to enable/disable oversubscription

> This flag lets an operator control cluster level oversubscription.
> The master should send revocable offers to framework if this flag is enabled
> and the framework opts in to receive them.
> Master should ignore revocable resources from slaves if the flag is disabled.
> Need tests for all these scenarios.
